Hy, I have the following situation:
I am trying to change the design of my feedly-index page. (I can not change the HTML)
And I am facing a problem I coulnd't solve the past two hours.
In the HTML there are some div elements with random IDs and '_content' at the end.
Within these div's there is an img tag - what I want to do is to wrap this img-tag with an anchor-tag to make it clickable.
Situation:
<div id='{SOME_RANDOM_ID}_content'>
// a bit of text, a few <br> and some other tags here
<img src='LINK_TO_AN_IMAGE'>
</div>
What I want as outcome:
<div id='{SOME_RANDOM_ID}_content'>
// a bit of text, a few <br> and some other tags here
<a href='LINK_TO_AN_IMAGE'>
<img src='LINK_TO_AN_IMAGE'>
</a>
</div>
Is this even possible with CSS?
I could make it work with JavaScript, but the div's are loaded dynamically via AJAX:/
So the JavaScript Script would just run for the current div's but not the one which are loaded dynamically.
It's not possible with just CSS because CSS is meant or styling the page and not or adding dynamic elements to the page.
But we can do it using JS.
As you are creating those elements using ajax call. On the success callback of the ajax call, you can wrap the image with a tags.
for example:
$.ajax({
url : "/make.php"
}).done(function() {
var images = $("div img");
$.each(images, function() {
$(this).replaceWith($("<a href=''>"+this.outerHTML+"</a>")); //construct url dynamically via some variable
});
});
DEMO
If you are not able to edit the html this could be tricky.
It can't be done with pure css... css can't create links.. I mean it could be possible with js i suppose, besides that if the ids are random it makes it even more difficult.
--edit additional--
If you could wrap the whole area that holds the divs inside a div then you might have a chance with jquery...
e.g:
<div id="holderdiv">
<div id='{SOME_RANDOM_ID}_content'>
// a bit of text, a few <br> and some other tags here
<img src='LINK_TO_AN_IMAGE'>
</div>
</div>
You can then use jquery to make all instances of #holderdiv > div > img a link to the image path?

my HTML is:
<div>
<img src="random image (doesn't matter)"></img>
</div>
How would I make my div draggable like setting draggable = "true"; in html but I am looking for a css only alternative.
What I have tried:
I had a look at https://css-tricks.com/books/greatest-css-tricks/draggable-elements/ but this answer seem too complex and I feel like there could be a better solution.
Another question (Setting html tag attributes from css) was looking at setting a HTML attribute in css (in this case draggable) and I don't believe that it is possible looking at the answers.
HTML elements can't be made draggable using CSS only. You will need to use JavaScript to make an element draggable. You can make use of the HTML5 draggable attribute for this:
<div draggable="true">Your Content Here</div>
You can also use JavaScript libraries such as jQuery UI to make elements draggable:
$( "#yourElement" ).draggable();
Or use vanilla JavaScript and interact with the HTML5 drag & drop API:
const yourElement = document.querySelector('#yourElement');
yourElement.addEventListener("dragstart", function(event) {
event.dataTransfer.setData("text", event.target.id);
});
Note: that there are many ways to make elements draggable and the exact implementation depends on your requirements and the complexity of the drag-and-drop interactions you want to support.
Is it possible to insert -- dynamically generated -- content with CSS into the same website a second time, let's say a div-container like this: <div id="duplicate-me">dynamically generated content</div>
CSS is used to style content that exists or will eventually exist on a page. It can't load or insert dynamic content to a page. It can control showing/hiding content on a page, but the content needs to be placed there first (with the exception of psuedo-classes, but that's not really "dynamic"). As others have mentioned, Javascript/jQuery is what you are needing to use to achieve what you are wanting.
Using pseudo element's in CSS we can kind of create an element and style it in CSS. But then this has it's own limitations.
Javascript is what will essentially help you achieve this using document.createElement() method and other methods line appendChild() etc
CSS cannot be used for duplicating, but you can use javascript to duplicate div,p or any other element. We do it like
In the html file
<head>
<!--all other stuff-->
<script src='sketch.js'></script>
</head>
in the sketch.js file
var dupElem = document.createElement('div');
dupElem.id = "duplicate-me";
document.body.appendChild(dupElem);
//to manipulate the text content we do
dupElem.textContent = "some lorem ipsum"
//or else you can do a for loop
for (let i = 0;i < 3;i++){
document.body.appendChild(dupElem);
}
It is possible to make a copy of a node element but you need Javascript to do that.
<div class="duplicate-me">dynamically generated content</div>
In your Javascript:
let nodeToClone = document.getElementsByClassName("duplicate-me")[0];
let newClone = nodeToClone.cloneNode(true);
document.body.appendChild(newClone);
Please note that id needs to be unique in the document. That is why I used class.
Here you can learn more about clone.
O.K., JavaScript then. I'll look into it. Thank you for the answers. :-)
I read about semantic HTML online...
Semantic HTML means using HTML tags for their implied meaning, rather than just using (meaningless) div and span tags for absolutely everything.
If you use <h1> instead of <div class="header">, and <h2> instead of , et cetera, Google and other search engines will interpret your headers as being important titles in your page. This way, when people search on the words in your headers and sub-headers, your page will be considered more relevant (and rank higher). Plus, it's much shorter and cleaner.
So, below is semantic,
<h1>My Website Name</h1>
<h2>My Website Tagline </h2>
What about this below?
<div id="header">
<h1><span class="hide">My Website Name</span></h1>
<h2><span class="hide">My Website Tagline</span></h2>
</div>
I tend to combine h tags with div and span tags like above - is this practised considered as the lack of semantic?
The reason why I have the span with the hide class is that I want to display the site logo instead of text. So use CSS to set the background of h1 as image and then hide the text. is this incorrect practise?
Then, if I don't use div, what can I use to make a box around the h1 and h2?
As far as I know, html 5 is not fully ready yet, we must not use <header> yet, must we??
Thanks.
I would do something like the following if I was going to use HTML5:
<header>
<hgroup>
<h1>My Website Name</h1>
<h2>My Website Tagline</h2>
</hgroup>
</header>
Remember to add display: block; to the HTML5 elements and createElement for IE in the CSS though. The header element shows the block is a header and the hgroup element is there to show that the second h* element is a sub heading, so shouldn't be taken into account when calculating the header levels in the document.
If you don't want to use HTML5 yet then you could use divs instead of the new elements, and use the HTML5 element names as the class value. This will make it easier to switch over when you feel comfortable using HMTL5 on a live site.
You don't really need to use the span elements. You can use tricks such as using a large negative text-indent in the CSS to hide the text off the screen.
If you want to display a logo instead of text, use an image. Google say so (even if they don't know the difference between a tag and an attribute). Taglines, BTW, are not subheadings (and the site name (and thus logo) is usually only a heading on the homepage).
<div id="header">
<h1><img src="foo.png" alt="My Website Name"></h1>
<p><img src="foo.png" alt="My Website Tagline"></p>
</div>
Unfortunately, Internet Explorer 8 does not recognize many HTML5 tags, and when I've tested it, I was unable to set CSS values for the <header> tag, for example. So for now I would recommend that you continue to use div tags to group your semantic meaning.
As a sidenote, Google does not like hidden text, and if you have a lot of it, it will consider it deceptive coding. One is probably fine, but you'd be better off using the alt attribute on the image tag.
Nobody suggested that you should not use DIVs at all... semantic HTML does not mean there cannot be div or span tags in your code. It just only means that whenever possible (there is a specific tag available for a specific semantic meaning) you should try to give semantic meaning.
h2 is not to be used for taglines, as somebody else already suggested.
Also, in my interpretation (some will argue), h1 is not for the name of your website. It is the title for the content on a specific page.
I agree with #David Dorward, the tag line should be in a p tag.
Your example (wrapping the header elements with a div) is perfectly acceptable, though I would like to raise a small caution: Be careful that you do not get in the habit of wrapping everything in div tags. For example:
<div class="content">
<div class="list">
<ul>
<li>something</li>
<li>something</li>
<li>something</li>
</ul>
</div>
</div>
Since a ul tag is already a block element, the above markup would be better off like this:
<div class="content">
<ul class="list">
<li>something</li>
<li>something</li>
<li>something</li>
</ul>
</div>
And then just style the ul to look like the div.
On the matter of displaying the logo as an image:
If your logo is text-based, or has text in it, you would be better off doing the following:
HTML
<div id="header">
<h1 class="logo">My Logo Text - My Website Tagline</h1>
</div>
CSS
.logo { text-indent:-9999px;background-image:url(thelogo.jpg) no-repeat;}
/* Also add height and width based on your logo height and width */
The title pretty much says it all. There are tons of scripts out there that do so, but most of them are so bloated and end up messing up script, and just use info from alt tags. My script goes as follows:
<ul>
<li style="display:block">
<img src="images/portfolio/talktostrangers/1.jpg" />
<div class="caption">
<span class="projecttitle">Talk to Strangers</span>A social awareness campaign that proposes people talk to strangers on trains, subways, elevators, & the like.
</div>
</li>
</ul>
The preview can be viewed here to get an idea of where it will go: http://www.studioimbrue.com/beta
If I understand correctly, you just want the caption to show when hovering over an image. The best way to do that is with javascript. I recommend using a js Framework, like jQuery, which makes it really easy. You can just include the jQuery source code and put this in a script tag or an external file within the head of your document.
$(document).ready(function(){
$('li img').hover(function(){
$(this).siblings('div.caption').fadeIn('slow');
}, function(){
$(this).siblings('div.caption').fadeOut('slow');
});
});
Then it's all about css styling, opacity, background-color, text-color. Up to you.
Regarding the 100% width in the title of your question, because it's in a DIV tag, it should automatically fill 100% of it's parent, the LI.
I've got a DIV I want to hide, but I cannot give it a specific ID... actually I cannot change the text of the DIV, since it is retrieved from a database, but I can add some html before it AND I know the exact text content of the DIV.
It's something like:
<div class="this_div">content_of_this_div</div>
So, I thought that maybe looking for the specific content, then taking the div and incapsulating it in a hidden div could work... or something similar... any idea?
thanks
If you can insert other HTML around it then you can use another div to hide it
Using CSS and HTML
.hidden { display: none; }
...
<div class="hidden"><div class="this_div">content_of_this_div</div></div>
Using HTML and Inline CSS
<div style="display: none;"><div class="this_div">content_of_this_div</div></div>
Wrap it in your own div would seem most sensible.
<div id="mydiv">
<div class="this_div">content_of_this_div</div>
</div>
then hide your div:
document.getElementById("mydiv").style.display="none";
Or, use jQuery. If that is only instance of class, you could do
$(".this_div").hide();
If you just want to be able to select it without giving it a specific id, you can do a number of things. Make an empty div with an id before, then use the direct sibling selector:
#divid+div {}
or use many other css selectors to accomplish same
But I do reccomend the aforementioned external div technique over this
