I need to know if it's possible to load text from a TXT file with the CSS "content" attribute? I searched around and didn't find anything.
I have the following CSS:
.custom div.ot-loginPageCopyright::after {
content: url('copyright.txt');
text-indent: 0;
display: block;
line-height: initial;
}
The browser does request and download the .txt file, but nothing is displayed. It will display the text when it is a string literal in the CSS, but I was hoping to have some copyright information stored separately from the CSS in a text file, in case it needs to be updated, you could just update the text file without touching the CSS.
Note: I know how to do this via JS, but this has to be done via CSS, as no changes can be made to the HTML or JS. So please: no comments suggesting that this should be done in some other way except CSS (if it's possible).
Thanks!
Thanks for the comment #rawnewdlz! I saw the hack for using a SVG, but I was wondering if it was at all possible feeding in a text file into the content, which is not possible.

How can I add CSS to github's markdown language?
I've been able to do so by using the style property inside html tags, like:
<p style="text-align: center;">This is some random text</p>
But if I move the css to the beginning, like:
<style>
p {
text-align: center;
}
</style>
<p>This is some random text</p>
Github doesn't recognize it, and just writes to the screen the css code.
I'm using Atom, and the package Markdown Preview actually recognizes this correctly, even though on the remote repository it shows wrong. And so does the Google Chrome extension Markdown Preview Plus.
Is there a way to do this? Writing css within html tags just feels plain wrong.
After GitHub converts Markdown to HTML,
The HTML is sanitized, aggressively removing things that could harm you and your kin—such as script tags, inline-styles, and class or id attributes. See the sanitization filter for the full whitelist.
style tags are not included in GitHub's whitelist, so they are removed. I'm actually surprised that inline style attributes work; they don't seem to be included in the whitelist, either, and are explicitly mentioned in the previous paragraph.
In any case, GitHub does not permit arbitrary HTML to be included in Markdown.
Here is how you can accomplish what you're looking for. As the other answer states, Github doesn't support this syntax, but if you pop this Markdown into another preview tool you'll see that the bullets are removed from this list.

You can trivially override what CSS Github uses by supplying it with your own style.css file, nested as ./assets/css/style.css (which is stylesheet URL that gets pointed to in the HTML source code that Github build off of your markdown).
Note that if you want to just "add" any CSS, you'll want to copy Github's CSS first, so you can create a file with the same content after which you place your own rules. You can find this on any view-source:https://username.github.io/repo-name/assets/css/style.css with the obvious replacements for username and repo-name.
E.g.
/* CSS as copied from github's own stylesheet here, which is all one line anyway */
...
/* And then your own CSS */
/* remove the repo name as some kind of weird super-title */
h1:first-child { display: none }
/* and better emphasise the _real_ title */
h1:nth-child(2) { font-size: 3em; }
/* let's also give images a subtle border */
img { border: 1px solid #DDD; }
On the homepage of my developing ecommerce store just below the carousel, there is an image under the H1 "I Wish I Were Knitting..." that has a paragraph sort of wrapped to it.
I have applied a float class to the img tag which is located within the p tag. I have one line of text floating correctly by removing the bootstrap img-responsive class from the img tag.
Why won't the full paragraph wrap? I would put markup and CSS in this text here but because this code in question is part of a huge .asp system, I wonder if folks would please check out the markup and CSS with the Inspect Element on the page itself where you can see the other code and CSS around it.
I see you added class="floatleft" but you need to add the css float: left;. Tested using Chrome Dev Tools and it works :).
You can always add the class to your css using the following :
.floatleft {
float: left;
}
Then you will only need to change the CSS and not your HTML. Good luck!
I found my main error. It's an understandable error given the state of my development. Turns out I was editing the wrong css file. When I put my css in the correct file, everything worked. I'll examine your kind ideas and observations with appreciation. Yes, padding will help.
There are two CSS files referenced on the same page: A generic.css file and a custom.css file. The generic file has default styles in it that are overridden by the custom.css file for the same elements. This allows users of the site to customize or "skin" their pages without needing to recreate the entire generic.css file. Only a few styles would be overridden.
My question is the following: If the generic.css file has a style for an element with a background image and that same style is overridden in the custom.css with a different background image, is the first image ever downloaded by the browser?
Also, I want to find out if this is bad practice - customizing or "skinning" a generic CSS file with another custom CSS file to override a few styles, including specifying different background images.
While not totally definitive, this site ran some tests regarding this. The significant statement from that site that is related to your question is:
CSS images are kicked off not in the order in which they appear in the
CSS but in the order in which they’re called in the HTML. I’m not sure
of the precise moment when the download is initiated, but my guess is
that it happens just after the CSS rules have been matched, when the
property values are assigned to the DOM elements.
This at least tentatively confirms what I thought I remembered in the back of my mind reading on this a few years back, namely, that background images which are not ever displayed (as in the generic.css images being overridden by the custom.css images) are not ever downloaded.
Further confirmation of this would be the typical image preloader script that used to be so common prior to sprite images (and is still found in certain uses). It was designed to download images that would be used on :hover in css, because without it, the image would not load until the first hover was initiated, and this caused an unsightly delay. So that, also, argues for the fact that unless actually displayed (or preloaded), the background images themselves are never loaded.
I don't think there are generally any issues with "skinning," unless you are essentially overwriting most or all of the generic.css with custom.css, then one could argue, why load the generic at all. But as you said, normally there are just a few styles overwritten.
I think i answered NO and NO BAD PRACTICE. Because when the css file readable / executable by the browser, the browser will make comparisons to find the same value or the difference between css file and then combine them.
Easy example:
css1.css on file there is a line:
.test {display: block; width: 100%; height: 600px; background: #991100 url("image1.jpg") center top; border: 1px solid red;}
then the css2.css there is also the line:
.test {background: #991100 url("image2.jpg") no-repeat center center;}
the result of a combination that will be executed and run by the browser are:
.test {display: block; width: 100%; height: 600px; background: url("image2.jpg") no-repeat center center # 991100; border: 1px solid red}
where the "background: # 991100 url("image1.jpg") center top;" read but not called / executed by the browser.
Far as I know the value of the file css1.css be stacked by the value of the css2.css. What if there a css3.css file? then the file css3.css will also stacking on the combination of css1.css and css2.css.
Hope it helps.
I’ve got the following CSS to add a PDF icon to any link that links to a PDF:
a.pdf-link:after { padding-left: 2px; content: url(../images/icon-pdf-link.gif);}
Is it possible to put some title and alt attributes on this image? I would like it so that the user is able to hover over the icon and get some text like “This links to a .pdf file.” Which I’ve typically done just by putting title attributes to it, but can’t figure out if I can do that through this method.
No, content only accepts raw text and image data, not HTML.
You need to use JavaScript to dynamically add tooltips to your existing HTML elements.
As for the icon, you could use a background image and some padding:
a.pdf-link {
padding-left: 2px;
padding-right: 20px;
background: url(../images/icon-pdf-link.gif) right center no-repeat;
}
If you need to specifically have a tooltip only on the icon, though, you need to do everything in JavaScript as the comments say.
You can this, these days, using CSS3.
According to https://www.w3.org/TR/css-content-3/#alt:
1.2. Alternative Text for Speech
Content intended for visual media sometimes needs alternative text for speech output. The content property thus accepts alternative text to be specified after a slash (/) after the last . If such alternative text is provided, it must be used for speech output instead.
This allows, for example, purely decorative text to be elided in speech output (by providing the empty string as alternative text), and allows authors to provide more readable alternatives to images, icons, or text-encoded symbols.
Here the content property is an image, so the alt value is required to provide alternative text.
.new::before {
content: url(./img/star.png) / "New!";
/* or a localized attribute from the DOM: attr("data-alt") */
}
Based on the answer I just did the following with jQuery:
$(".pdf-link").before("<img src='../images/icon-pdf-link.gif' title='This link is a pdf' />");
When I save a document in CKEditor (CKEditor 3.5.2), the saved HTML is right. But when I open that HTML again for editing (putting the HTML in a textarea and then load CKEditor), CKEditor parses the style setting wrong.
If I have a code that looks like this:
<div style="font-family: arial; font-size: 11px; background: green;">Hello</div>
And then open it with CKEditor, it looks like this:
<div style="font-family: arial font-size: 11px background: green">Hello</div>
The ; has disappeared. It does not matter which style settings I use, the semicolon disappears in all cases.
It does not matter what element the style setting is in. The same problem appears in img, div, a, span... and so on.
What shall I do? I am about 100% sure it is ckeditor that is the problem. I open the HTML right from the database. But what else than ckeditor could it be?
I do not use any CMS site, just pure php.
might be some configuration issues.
reinstall properly because i am also using ckeditor it's works fine in all browser and support all kind of html or css tags
