I am first time poster. A question. How do a make a css declaration that only works within one DIV, but, not overwriting the global css? I want to jQuery loading a page into a DIV, however, the page's CSS changed my own site's CSS. I don't want that. Also I can't just take out CSS because I want them looked as intended from the source.
Basically we are going to load an external HTML with its CSS style applied locally ONLY without it changing the style elsewhere. The external HTML is not using inline CSS since we don't have control over it. They are applied to class values or even all element type. We don't want their CSS declaration modifying our own existing CSS outside of the DIV container.
Is this even possible?
Thank You?
If I understand your question correct you would place an id in the div <div id="mystyle"> content </div>. In your CSS you would write #mystyle p { color:red; }. which have no effect on global paragraphs outside the "mystyle" div.
I guess you are asking how to apply an external stylesheet to just one div. There is no way to do this using just CSS. You might be able to emulate this using JavaScript, but it's going to take quite a bit of work. Here's an outline of how you might go about doing this:
Grab the stylesheet filename from the loaded HTML and then get the contents of the CSS file via AJAX.
Somehow parse the CSS and prefix your div ID to each CSS rule, so that it applies only within your div.
Inject the modified stylesheet as inline text into the loaded HTML.
Steps 1 and 3 are relatively simple, step 2 requires a CSS parser written in JavaScript. (There seems to be one available here although there is no documentation.)

I set up a background image with css (background-image) in the body tag of the template so that only shows in the pages generated with it, however that's affecting all 'body's in the entire gatsby.js website.
This is normal behavior. It's not a Gatsby issue. It's how React's templating/code-splitting works.
You are defining a CSS rule in your isolated CSS but it's bundled when the project is compiled (because of webpack) and because of the specificity, it affects all body tag. In the end, your template will be also injected into the output HTML so all the imports in it will also merge in the final output.
The easiest and most straightforward solution I think is to define a <section> (or another tag) just as a direct child of the body for each template/page you want to customize and give a specific class name to apply the CSS only to that template/page. Increasing the specificity is the easiest way to apply.
Soon, in the new Chromium version (99) we will be able to define layered components in order to enhance the specificity and improve that kind of behaviors you've described.
I was looking for a (simple) WYSIWYG Editor jQuery Plugin that's compatible with Bootstrap 3. I've seen a lot WYSIWYG Editors jQuery Plugin that were compatible with the previous Bootstrap, but my website uses Bootstrap 3, so each time I implemented such a jQuery Plugin, my Bootstrap 3 would ruin the buttons and mess the whole editor up.
So now I'm asking whether there is an option to enable the Bootstrap 2 stylesheet only for one div and its contents.
I assume a iframe could work, but then, I need the WYSIWYG Editor's contents (which are in the iframe then), along with text inputs on the 'non-iframe'.
One way you might be able to solve this would scope your css for that div. This is what I have implemented with a content management system that I have created.
Let say for example you give the WYSIWYG Div an ID of HTMLEditable.
you could target that div with your css and all the css within that div.
#HTMLEditable .WYSIWYG{
....css goes here
}
#HTMLEditable p{
....css goes here
}
The above css will only apply to that div.
Then its just a case of finding the correct css that you need in that div.
Note you may need to override/reset the css for that div to stop your bootstrap3 applying to it.
Here is an example of a reset css. (You will need to scope this as well to make sure you don't reset all your css).
EDIT: use LESS
To make this easier you can use LESS which is what bootstrap uses.
#HTMLEditable {
//import the modal css
#import "bootstrap.css";
}
you will need to make a file 'HTMLEditable.less'. Then Add the code to similar to the above.
The less will them compile the above into css and will scope everything in the css to #HTMLEditable
Check out the LESS site and look ate the nesting. This is what you are after. This site will also show you how to compile it.
You need to put the class or id of this div before all css rules. You can do it like this if you need a css file and not less.
#HTMLEditable{
paste in all of your css
}
than copy all of this paste it here: http://less2css.org/ in the less area and it will generate the right css for you.
I built an extension which, whenever user visits some specific sites, I inject my script on the top of there web pages. I used
document.body.insertBefore(wrapperDiv, document.body.firstChild)
to do so.
Now problem: CSS of injected script gets messed up for each and every site(differ from one site to another).
How should I maintain single css structure for all sites?
You should be able to solve this problem by using unique IDs for your html tags with CSS.
That is, if your DIV CSS properties are interfering with their DIV CSS add a #uniqueNameHere ID to your DIV and set the CSS for the #ID.
This page on the use of the !important keyword may be useful too.
http://css-tricks.com/9462-when-using-important-is-the-right-choice/
Use unique selectors for your elements (be it classes with specific prefix or similarly constructed IDs), but you probably try to include CSS along with your script, which may not be a good idea.
In some cases the inline styling is the best idea - it will overwrite all the styles for your elements and will make sure the outlook of these elements is consistent across different pages.
So, I would say, go with inline styling.
For documentation on how the styles are overwritten in CSS 2.1, please see the following page: http://www.w3.org/TR/CSS21/cascade.html#specificity
I have made some templates on wikia.com, which contain only CSS code (key:value;).
My problem is having another template use these style templates in a style attribute tag.
style="{{MyTemplateStyle}}"
This code does not evaluate as expected. The CSS code is outputted before the element and the style attribute is not included inside the element.
Am I trying something not possible for a wiki ?
I merely want to be able to change styling on certain templates in one place, like regular HTML & CSS pages.
CSS styling specified from the style="" attribute always takes priority over any other css, even if you use !important in a CSS specification.
Therefore any edits you make to your CSS on Wikia will not ever override the CSS specified inside an attribute.
Kim, you were right to switch to classes instead of embedding in-line styles via templates.
The very idea of using templates suggest that this was going to be re-used in more than one place, applying styles to a group or, in fact, a class of elements.
This approach is much simpler to read and maintain (as you only have one, central place to edit), and also, if done right, will enable you to seamlessly change the colour scheme via Special:ThemeDesigner.
I have a div- workarea, where, I want to load contents of body of a template. I could load the content, but how to load css of the template. If I tried to load it, it overrides the default css of the page into which I'm loading the template's body content. I don't want to use iframes in my project.
Thanks in advance
Another alternative is to create a reset stylesheet just for that div container. Put aa id selector on the container div in which you load content and use that ID as a prefix for styles you use in the template.
<div id="template_content"></div>
and css as
#template_content h2 {....}
#template_content p {...}
If you cannot do this than your only option is iframe.
Your only simple option here is to use an <iframe>, styles cascade down, that's just how they work and were intended to work, if you want a section of the page with drastically different styling that also doesn't inherit, an <iframe> is the perfect tool do this.
Many people think frames are bad, that that's a different thing from iframes, no matter which side of the line you're on <iframe> elements are perfectly legitimate to use here. Why try to solve the problem in a very round-about way when the perfect tool for the job is laying there ready to use?
For example this is how almost every rich-text-editor works in a page, via an <iframe>, for many reasons but to keep the styling separate is one of them :)
Give Some id to that div like WorkArea. Now in css file, write your styles and from. Do not attach anything to any divs of the body from css, using body as parent class
might be hard but give the display or preview area important dominance...
like...
#template_content {
background: green !important;
}
then when you load in another style sheet, #template_content's background cannot be changed unless you have !important defined on the stylesheet you are loading in.
