I have a page from which I call fancybox which contains some html template (something like an email template). The problem is that all CSS from the main page affects the content in the fancybox and vice versa. What I would like is to isolate them somehow, so that their CSSs don't affect each other.
Example: I have background image set for h3 for the main page. Also, in fancybox I have h3 element which has no CSS assigned to it, but it pulls the style from the main page and gets the same background image (which shouldn't happen).
Is this somehow possible?
You could split your CSS into multiple files, only pulling in what you need to for each html. If you aren't able to do that you can give the body a specific #id for your template that gets loaded into the fancybox.
<body id="fancy_content">
and then adapt your styles for that template
body#fancy_content h3 {
color: green;
}
You may still end up with a bit of style clash if you leave it in one file but this will give you a method to go on to get it working.
You have 3 options really.
Run the fancybox content in iframe mode which means the content will have to be on it's own page without the main stylesheet. You can do any styling you like here or none at all.
Reset styles in the fancybox content, though this may be quite tedious depending on the number of elements affected.
Place the fancybox content outside the main #wrapper div of your page, and make all page styles inherit from #wrapper. i.e. instead of h3 {...} use #wrapper h3 {...}
try adding IDs to your html elements then use CSS IDs
h3#idname { color: #FF0000; }

So my site is locked at the top of the browser which is correct, however when I hit reload (command + R) on this gallery page it now vertically centers everything which is not what I want. It's a template based site (squarespace) with stuff I have added.
I added this css:
#canvas { top: 0 !important; margin-top: 0 !important;}
and this HTML
<script type="text/javascript">
window.onload=function(){
document.getElementById('canvas').removeAttribute('id');
document.getElementById('canvasWrapper').removeAttribute('id');}; </script>
When you first load the page, you have a div (with ID something like "yui_3_10_1_1_1376940471763_412") that has no inline styling. So everything looks fine.
When you reload the page, that div no longer has an ID, and instead has an inline top margin added to it, apparently by Javascript, which pushes your site down.
Meanwhile, your code makes no sense. You've applied CSS to the div with id="canvas", and then used Javascript to remove that id, giving your CSS nothing to apply to.
Having removed that, your page is also throwing a JS error because a SquareSpace function in site.js is looking for the IDs you've deleted.
I'd try removing your added JS (leaving "canvas" and "canvas-wrapper" intact). Your CSS (with the "!important" tags) should override any inline styling that SquareSpace adds.
I have created a UI (for wordpress plugin) in which I give user choice to add text, image, and video in a div ( lets call this div, container).
I have been working on it for a quite sometime. I recently added tinyMCE (WYSIWYG editor) to add text inside container.
Now, I realized that I did a big mistake. The text user writes is being overridden by css rules defined for wp admin panel.
for example,
User enters <h1>Hello</h1> (with the help of tinyMCE), and then I grab that content from tinyMCE and append that in the container.
But here the problem arises, wordpress's admin css can have css rule like this,
h1 {
color : #d6d6d6;
line-height: 40px;
font-size: 30px;
}
So, it looks different in tinyMCE and in my container. (as tinyMCE's code is inside iframe and that remains unaffected by wordpress's css rules, but my container doesnt)
I want something so that any element inside container remains unaffected by wordpress's admin css.
I know a good solution would be putting container inside iframe. But I have written a lot of code without thinking of an iframe and I would need 3-4 days just to adjust everything for iframe. There may be some cross browser issues.
I can reset some wordpress rules, but it will fail sometimes, as user may enter anything. I need something fullproof.
well if you want to undo a specific rule (say the h1 rule you mentioned) you can use css to override it by being more specific.
.container h1 {
color:#000000;
line-height: 24px;
font-size: 24px;
}
This will overwrite the css rule you mentioned with the given values but only when the element is inside the container class, (I'm guessing at the default values you want to use.)
Unfortunately you would have to add in an undo rule for everything that wordpress's admin css changes.
Another possible solution is to edit the page tinyMCE returns in it's frame to add in wordpress's CSS file. This means the end user will see the same formatting when they enter the information as when it gets posted.
Do you have code-level access to the iframe contents tinyMCE creates?
Use !important in your CSS document. This way your CSS will not be overridden as it takes precence over everything, including inline styles.
h1 {
color:#ff0 !important;
}
In my site I am stick with some CMS. In my cms there is some sticky layout.
Now My client needs two different look on it.
So when I am on "homepage" my DIV class test show different and when I am on other page so that same class work different.
This is for home page
.test {
some data
}
This is for Other Page
.test {
some data
some data
}
So is there any way to make condition in css that if my URL is homepage so call this otherwise call this.
You should add a custom class on your body, like the page name.
<body class="home">
...
</body>
<body class="my_page">
...
</body>
Then you can have a different style for each one.
.home .test {
background: red;
}
.my_page .test {
background: blue;
}
You can't use CSS to detect the URL. So, you'll need to detect the URL with JavaScript (like this), or better, detect it on the backend.
Same css wont work differently for different pages(URLs), One way you can do is changing the inline styles with JavaScript. But it will be painful if you suppose to change a whole style-sheet.
Other way is, it is more than detecting the URL, you need to change the style-sheets dynamically for different pages. Different style-sheets may have same classes but with different styles.
Therefore, create separate style-sheets and apply dynamically.
You can get some idea about changing style-sheets dynamically here
You could use JavaSctipt to detect the URL, and then again use JavaScript to add an extra class to the body if you are on the home page. You then write separate CSS styles for elements contained within this new class.
I have two css files:
A main file (main.css)
A specific page file (page5.css). My page.css contains main.css (#import url(main.css));)
My main.css has this as one part of it that sets the height of the page
#content {
background:url(../images/image.png) no-repeat;
width:154px;
height:356px;
clear:both;
}
This works fine for all the other pages, but at page 5, I need a little bit more height.
How would I go about doing it?
You don't even need a separate CSS file necessarily. You can add classes to your body for various purposes, identifying page or page type being one of them. So if you had:
<body class="page5">
Then in your CSS you could apply:
.page5 #content {
height: XXXpx;
}
And it would only apply to that page as long as it occurs after your main #content definition.
Just re-define it somewhere after your #import directive:
#content { height: 456px }
for identical CSS selectors, the latter rule overwrites the former.
In page5.css, simply re-define the height.
page5.css
#content {
height:400px;
}
The other answers did not help me on a more complex page.
Let's suppose you want something different on page X.
On your page X, create a class at the body tag (body class="myclass").
Open the Developer tools (I use chrome) and select the item to be modified. Let's say it's a link ( a.class - 'class' is your class name of your anchor, so change it accordingly). The browser will give something rather generic that works on the developer tool - but messes up in real life.
Check the parent of the modified field.
Add the HTML tag to your developer tool as testing
f your new CSS path does not grey out, you are good. If it greys out, your selected path still needs fixing.
Let's suppose that the parent is a div with a class 'parent'. Add this path "div.parent >" to the already chrome selected a.class
The symbol > means you are going up on the tree.
You can keep going backward on the DOM all the way to body.myclass, or you may not need. There is no need to add the classes for the parents, but you can add them if there are great similarities on your pages.
This works for me.
I use CMS for client and client doesn't know CSS he use WYSIWYG editor to put content in pages. Client adds Paragraphs, images, images in paragraph (left or right floated), ordered and unordered list, Tables. Problems comes when he want to add images in paragraph (left or right floated). and without adding css class it's not possible. And i don't want to add <div> in content because WYSIWYG editor can't manage div and client works in WYSIWYG mode.
How to style content of pages without using css class?
You will need your user to add a CSS class/style attribute to the image somehow - without adding something to the image to tell it to float right or left it won't float right or left.
If your question is how the client can add the class without having to manually edit the HTML I reckon the only way is to dive into the WYSIWYG editor's javascript and write something a bit like this towards the end of the image-adding process:
var alignment = prompt("Type l to align the picture to the left, and r to align the picture to the right","l").strToLower();
if(alignment == 'r')
{
//line of code to add class "right" to the image tag
} else {
//line of code to add class "left" to the image tag
}
What the code to add the classes should depend on how the WYSIWYG editor works
You can try using element selectors or ID selectors to add styles to HTML elements without referencing CSS class in them.
Element selector would add border to all images on the page:
img { border:1px; }
ID selector would do the same only to image with ID 'image1':
img #image1 { border:1px; }
Still you will need to reference the stylesheet from your page.
There are lots of different ways you can make CSS Selectors that don't require CSS classes. For example, to make a rule that applies to all img tags inside p tags, you could write this:
p img { float: left; }
But how are you hoping to determine which images need to be right-aligned and which images need to be left aligned? Does that data exist in the document in any machine readable format?
A WYSWYG should have "align" property for an image (at least those I have seen). You can then use CSS attribute selector img [align=left] { float:left; } or img [align=right] {float:right;} This wont work on IE 6,7 though, you can use JavaScript to mimic this for those browsers.
