Single Stylesheet Multiple Pages Dreamweaver CS6 - css

I have 2 pages that share the same stylesheet. How do I make changes to one, without affecting the other? I am new to coding, so please be specific as possible.
For Instance: I have a main image on the HOME page and want to delete it on the PRACTICE AREAS page but whenever I do so it deletes it on all pages.
Help please, and thank you in advance!

A good practice for styling pages differently is to have a class name applied to the body or to the enclosing div which corresponds to the page, e.g.:
<body class="home">
<div>Content here</div>
</body>
This gives you greater specificity, so in your CSS, you could be writing:
.home div {
background-image: url('your-image.jpg') no-repeat left top;
}
... or some such.
But, it sounds like the image on your home page is content, rather than its presentation. In that case you should be including it in the HTML rather than the CSS.
<body class="home">
<div><img src="your-image.jpg"> Content here</div>
</body>
Does that help?

As far as I know, you can not do conditionals with CSS. I suggest you create a second style sheet for your "Practice Areas" page and simply override the style element showing the main image. For example
/* On main style sheet */
body
{
background-image: url(../graphics/main_page.jpg);
}
/* On Practice Areas style sheet: */
body
{
background-image: none;
}

Resize an image within a parent element class

This seems simple enough but I am trying to override a style class on an image tag.
A user uploads content and images using the CKEditor wysiwyg. The issue is if the user doesn't resize the image before posting and then I try to show their HTML on the page the image is wider than the container.
How can I override it with CSS?
<p class="post-content text-muted break-text mb-none">
<p><img alt="" src="https://example.com/1234.png" style="height:1598px; width:1594px" /></p
</p
I tried this css but couldn't override it.
<style>
.post-content img {
width:400px !important;
}
</style>
Since this is user-generated content, I can't add a class directly to the img otherwise I would, if that makes sense. Thanks
Your HTML has a <p> tag inside a <p> tag so would likely have rendered as two separate paragraphs, and the one containing the image wouldn't have the .post-content class on it.
Aside from that, you might be best of with this CSS, as this will keep the image at 100% width but no larger than its actual size.
.post-content img {
max-width: 100%;
height: auto !important;
}

CSS classes within classes

I have a page where I'm trying to use a lot of CSS.
I have a main wrapper class with background and everything and then a content class within that. Within the content class I then have IDs for various articles.
Within some of these articles I'd like images aligned to the right, but I don't seem to be able to do this.
From what I know
<div class="article">
In 1904, Sunderland's management was embroiled in a payment scandaat he would repay the money after his benthe money, claiming it had been a gift. An investigation conducted by the as part of a "re-signing/win/draw bonus", which violated the Association's rules. Sunderland were fined £250 (£20 thousand today), and six directors were suspended for two and a half years for not showing a true record of the club's
<div class="picha">
<img src="image/test.png">
</div>
</a>
</div>
should apply picha (i.e. align right, set a border) to the image...but it doesn't.
How is this handled?
Or better yet is there a way to set rules for images within a ID that isn't specifically for images? i.e. text is handled one way but all images posted in that id get special treatment.
edit- so updated attempt:
css has:
div.article {
border: solid;
background-color:red;
}
div.article img{
border: 10px solid #f1f1f1;
float: right;
}
and page has:
<div class="article">
<a name="article1">
random text
<img src="image/test.png">
</a>
</div>
The image shows and alligns right but is below the text and outside the text's box, I'd like it quite neatly inside the article box but to the right.
If I add float left to the text then the article box stretches but the image remains below the text.
edit2- and I'm a stupid newbie. Had to have the image before the text. Done!
If you want to access this nested div, you can either do as #Aquillo said.
Or do this:
.article .picha
{
/*Your css*/
}
and
.article .picha img
{
/*Your img css*/
}
Why don't you use?:
div.article {
// This applies to all content
}
div.article img {
// This applies to the image
}
div.article span {
// This applies to everything inside a span
}
You could write your text inside a span like this:
<div class='article'>
<img src='' />
<span>My text</span>
</div>
This way you don't need a wrapping div for you image.

Hiding contents without hiding the div?

This may be the simplest question ever, but try as I might I simply couldn't figure it out. I'm working on a website right now and I wish to use as few <div> elements as possible to keep the HTML pretty and easy to edit. At the moment I essentially have:
<html doctype etc etc>
<head>
<title and meta tags>
</head>
<body>
<div id="wrapper">
<div id="header"></div>
<div id="body"></div>
<div id="sidebar"></div>
<div id="footer"></div>
</div>
</body>
</html>
Very simple and elegant, yes? However the client wants their header to consist of a single large image which contains their company name and logo. So my options were pretty clear - either use an <img> tag, or set the background-image property on the header <div>. However then I got to thinking about SEO. For Google's sake it would be nice if the header <div> contained an <h1> element with her website's title, but then this element would have to be hidden so that human users only see the background image.
Although if you were to use the display:none; css property then the entire <div> disappears, including the background. Is there a good way to hide the contents of a <div> without hiding the <div> itself?
Have you tried to apply the hide on the H1 itself?
<div id="header">
<h1>Company title</h1>
</div>
Your style would be: #header h1{display:none;visibility:hidden;}
UPDATE
Apparently, we're both just having one of those days. If you want to make the H1 truly SEO/Screen reader friendly, it would be better to do this with your CSS:
#header h1{
width:XXXpx;
hight:XXXpx;
background:url('image/location.png');
text-indent:-9999px;
overflow:hidden;
}
This way your text is actually there on the page and rendered, it's just kind of off screen.
You could replace #header div with h1 if you want this tag, set background image on said h1 and even put some text in it (company name) and use text-indent to hide it.
Plus, in your quest to minimize number of elements you can use body as a wrapper, and if you need full page background just set in on html element.
Set display: none on the H1 tag rather than the div, and use the background image on the div.

DIVs not abiding by CSS rules

I'm having some troubles with my HTML and CSS, in that the HTML on my siet isn't doing what I've put down in the CSS.
I'm trying to make a block of text have width: 50, but it doesn't seem to be working.
Here's a code snippet:
<div id="welcome">
<h2>Welcome!</h2>
hello, this is some text.
<p>
text before that text down there. v
<p>
we have some text here.
<p><img src="images\halo.jpg" width="250" height= "250" alt="Master Chief" /><p>
</div>
This is from the site. I've put some rules down in the CSS to make this DIV, and other DIVs on seperate pages, have a width of 50%, but it just isn't working. Here's the CSS rule:
#welcome, #about, #contact {
width: 50%;
}
All my other CSS is working, and the HTML is correctly linked to the CSS. What am I doing wrong?
I've tried force-reloading, only having the rule for one DIV, and everything like that. If you can help me, thanks!
EDIT: Solved, thanks to ob. Cheers again.

try adding this to your page styles:
html, body, form { width:100% }
The style definition seems OK.
Do you have any other style defined for div?
Is it working on some browsers and not on others?
You can easily diagnose the problem with web-developer tool or firebug.
This kind of problem often is the result of 50% width combined with 1px border. It's 50% + 1px, and therefore more than 50%.

Make a div into a link

I have a <div> block with some fancy visual content that I don't want to change. I want to make it a clickable link.
I'm looking for something like <div> … </div>, but that is valid XHTML 1.1.
Came here in the hope of finding a better solution that mine, but I don't like any of the ones on offer here. I think some of you have misunderstood the question. The OP wants to make a div full of content behave like a link. One example of this would be facebook ads - if you look, they're actually proper markup.
For me the no-nos are: javascript (shouldn't be needed just for a link, and very bad SEO/accessibility); invalid HTML.
In essence it's this:
Build your panel using normal CSS techniques and valid HTML.
Somewhere in there put a link that you want to be the default link if the user clicks on the panel (you can have other links too).
Inside that link, put an empty span tag (<span></span>, not <span /> - thanks #Campey)
give the panel position:relative
apply the following CSS to the empty span:
{
position:absolute;
width:100%;
height:100%;
top:0;
left: 0;
z-index: 1;
/* fixes overlap error in IE7/8,
make sure you have an empty gif */
background-image: url('empty.gif');
}
It will now cover the panel, and as it's inside an <A> tag, it's a clickable link
give any other links inside the panel position:relative and a suitable z-index (>1) to bring them in front of the default span link
You can't make the div a link itself, but you can make an <a> tag act as a block, the same behaviour a <div> has.
a {
display: block;
}
You can then set the width and height on it.
This is an ancient question, but I thought I'd answer it since everyone here has some crazy solutions. It's actually very very simple...
An anchor tag works like this -
EVERYTHING IN HERE TURNS INTO A LINK
Sooo...
<div id="thediv" />
Although I'm not sure if this is valid. If that's the reasoning behind spoken solutions, then I apologise...
Requires a little javascript.
But, your div would be clickable.
<div onclick="location.href='http://www.example.com';" style="cursor:pointer;"></div>
This option doesn’t require an empty.gif as in the most upvoted answer:
HTML:
<div class="feature">
</div>
CSS:
div.feature {
position: relative;
}
div.feature a {
position: absolute;
width: 100%;
height: 100%;
top: 0;
left: 0;
text-decoration: none; /* No underlines on the link */
z-index: 10; /* Places the link above everything else in the div */
background-color: #FFF; /* Fix to make div clickable in IE */
opacity: 0; /* Fix to make div clickable in IE */
filter: alpha(opacity=1); /* Fix to make div clickable in IE */
}
As proposed at http://www.digitalskydesign.com/how-to-make-an-entire-div-a-link-using-css/
This is a "valid" solution to achieving what you want.
<style type="text/css">
.myspan {
display: block;
}
</style>
<span class="myspan">text</span>
But most-likely what you really want is to have an <a> tag displayed as a block level element.
I would not advise using JavaScript to simulate a hyperlink as that defeats the purpose of markup validation, which is ultimately to promote accessibility (publishing well-formed documents following proper semantic rules minimizes the possibility the same document will be interpreted differently by different browsers).
It would be preferable to publish a web page that does not validate, but renders and functions properly on all browsers, including ones with JavaScript disabled. Furthermore, using onclick does not provide the semantic information for a screen reader to determine that the div is functioning as a link.
The cleanest way would be to use jQuery with the data-tags introduced in HTML. With this solution you can create a link on every tag you want. First define the tag (e.g. div) with a data-link tag:
<div data-link="http://www.google.at/">Some content in the div which is arbitrary</div>
Now you can style the div however you want. And you have to create also the style for the "link"-alike behavior:
[data-link] {
cursor: pointer;
}
And at last put this jQuery call to the page:
$(document).ready(function() {
$("[data-link]").click(function() {
window.location.href = $(this).attr("data-link");
return false;
});
});
With this code jQuery applys a click listener to every tag on the page which has a "data-link" attribute and redirects to the URL which is in the data-link attribute.
Not sure if this is valid but it worked for me.
The code :
<div style='position:relative;background-color:#000000;width:600px;height:30px;border:solid;'>
<p style='display:inline;color:#ffffff;float:left;'> Whatever </p>
<a style='position:absolute;top:0px;left:0px;width:100%;height:100%;display:inline;' href ='#'></a>
</div>
To make thepeer's answer work in IE 7 and forward, it needs a few tweaks.
IE will not honour z-index if the element is has no background-color, so the link will not overlap parts of the containig div that has content, only the blank parts. To fix this a background is added with opacity 0.
For some reason IE7 and various compatibility modes completely fail when using the span in a link approach. However if the link itself is given the style it works just fine.
.blockLink
{
position:absolute;
top:0;
left: 0;
width:100%;
height:100%;
z-index: 1;
background-color:#ffffff;
-ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";
filter: alpha(opacity=0);
opacity:0;
}
<div style="position:relative">
<some content>
<a href="somepage" class="blockLink" />
<div>
you could also try by wrapping an anchor, then turning its height and width to be the same with its parent. This works for me perfectly.
<div id="css_ID">
</div>
An option that hasn't been mentioned is using flex. By applying flex: 1 to the a tag, it expands to fit the container.
div {
height: 100px;
width: 100px;
display: flex;
border: 1px solid;
}
a {
flex: 1;
}
<div>
Link
</div>
This worked for me:
HTML:
<div>
WHATEVER YOU WANT
<a href="YOUR LINK HERE">
<span class="span-link"></span>
</a>
</div>
CSS:
.span-link {
position:absolute;
width:100%;
height:100%;
top:0;
left: 0;
z-index: 9999;
}
This adds an invisible element (the span), which covers your entire div, and is above your whole div on the z-index, so when someone clicks on that div, the click is essentially intercepted by your invisible "span" layer, which is linked.
Note: If you're already using z-indexes for other elements, just make sure the value of this z-index is higher than anything you want it to rest "on top" of.
why not? use <div></div> works fine in HTML5
This example worked for me:
<div style="position: relative; width:191px; height:83px;">
</div>
This post is Old I know but I just had to fix the same issue because simply writing a normal link tag with the display set to block does not make the whole div clickable in IE. so to fix this issue far simpler than having to use JQuery.
Firstly let us understand why this happens: IE wont make an empty div clickable it only make the text/image within that div/a tag clickable.
Solution: Fill the div with a bakground image and hide it from the viewer.
How?
You ask good questions, now listen up.
add this backround style to the a tag
> "background:url('some_small_image_path')
> -2000px -2000px no-repeat;"
And there you have it the whole div is now clickable. This was the best way for me cause Im using it for my Photo Gallery to let the user clik on one half of the image to move left/right and then place a small image as well just for visual effects. so for me I used the left and right images as background images anyway!
Just have the link in the block and enhance it with jquery. It degrades 100% gracefully for anyone without javascript. Doing this with html isn't really the best solution imho.
For example:
<div id="div_link">
<h2>The Link and Headline</h2>
<p>Some more stuff and maybe another link.</p>
</div>
Then use jquery to make the block clickable (via web designer wall):
$(document).ready(function(){
$("#div_link").click(function(){
window.location=$(this).find("a").attr("href"); return false;
});
});
Then all you have to do is add cursor styles to the div
#div_link:hover {cursor: pointer;}
For bonus points only apply these styles if javascript is enabled by adding a 'js_enabled' class to the div, or the body, or whatever.
This is the best way to do it as used on the BBC website and the Guardian:
I found the technique here:
http://codepen.io/IschaGast/pen/Qjxpxo
heres the html
<div class="highlight block-link">
<h2>I am an example header</h2>
<p>This entire box links somewhere, thanks to faux block links. I am some example text with a custom link that sits within the block</p>
</div>
heres the CSS
/**
* Block Link
*
* A Faux block-level link. Used for when you need a block-level link with
* clickable areas within it as directly nesting a tags breaks things.
*/
.block-link {
position: relative;
}
.block-link a {
position: relative;
z-index: 1;
}
.block-link .block-link__overlay-link {
position: static;
&:before {
bottom: 0;
content: "";
left: 0;
overflow: hidden;
position: absolute;
right: 0;
top: 0;
white-space: nowrap;
z-index: 0;
}
&:hover,
&:focus {
&:before {
background: rgba(255,255,0, .2);
}
}
}
<div> … </div>
Actually you need to include the JavaScript code at the moment,
check this tutorial to do so.
but there is a tricky way to achieve this using a CSS code
you must nest an anchor tag inside your div tag and you must apply this property to it,
display:block;
when you've done that,it will make the whole width area clickable (but within the height of the anchor tag),if you want to cover the whole div area you must set the height of the anchor tag exactly to the height of the div tag,for example:
height:60px;
this is gonna make the whole area clickable,then you can apply text-indent:-9999px to anchor tag to achieve the goal.
this is really tricky and simple and it's just created using CSS code.
here is an example: http://jsfiddle.net/hbirjand/RG8wW/
This work for me:
<div onclick="location.href='page.html';" style="cursor:pointer;">...</div>
You can give a link to your div by following method:
<div class="boxdiv" onClick="window.location.href='https://www.google.co.in/'">google</div>
<style type="text/css">
.boxdiv {
cursor:pointer;
width:200px;
height:200px;
background-color:#FF0000;
color:#fff;
text-align:center;
font:13px/17px Arial, Helvetica, sans-serif;
}
</style>
You can make surround the element with a href tags or you can use jquery and use
$('').click(function(e){
e.preventDefault();
//DO SOMETHING
});
This is the simplest way.
Say, this is the div block I want to make clickable:
<div class="inner_headL"></div>
So put a href as follows:
<a href="#">
<div class="inner_headL"></div>
</a>
Just consider the div block as a normal html element and enable the usual a href tag.
It works on FF at least.
I pulled in a variable because some values in my link will change depending on what record the user is coming from.
This worked for testing :
<div onclick="location.href='page.html';" style="cursor:pointer;">...</div>
and this works too :
<div onclick="location.href='<%=Webpage%>';" style="cursor:pointer;">...</div>
While I don't recommend doing this under any circumstance, here is some code that makes a DIV into a link (note: this example uses jQuery and certain markup is removed for simplicity):
<script type="text/javascript" src="jquery-1.3.2.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$("div[href]").click(function () {
window.location = $(this).attr("href");
});
});
</script>
<div href="http://www.google.com">
My Div Link
</div>
If you can use bootstrap, one simple solution is to use bootstrap .stretched-link.
https://getbootstrap.com/docs/4.3/utilities/stretched-link/
Sample Code
<div class="card" style="width: 18rem;">
<img src="..." class="card-img-top" alt="...">
<div class="card-body">
<h5 class="card-title">Card with stretched link</h5>
<p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
Go somewhere
</div>
</div>
Soviut's answer was not sufficient for me. I had to use
a { display: inline-flex; }
to remove baseline artifacts, when using just a img in the a.
Enclosing your div inside an anchor tag <a href></a> works like charm:
<a href="">
<div>anything goes here will turn into a link</div>
</a>
My smarty pants answer:
"Evasive answer to: "How to make block level element a hyperlink and validate in XHTML 1.1"
Just use HTML5 DOCTYPE DTD."
Didn't actually hold true for ie7
onclick="location.href='page.html';"
Works IE7-9, Chrome, Safari, Firefox,
if just everything could be this simple...
#logo {background:url(../global_images/csg-4b15a4b83d966.png) no-repeat top left;background-position:0 -825px;float:left;height:48px;position:relative;width:112px}
#logo a {padding-top:48px; display:block;}
<div id="logo"></div>
just think a little outside the box ;-)
