i use the CSS selector xmlns\:div for XMLNS to style my elements, but i cant use the tag elment selectors... for example div{color:#fff;}
NB: the XMLNS prefixes is generated automatically so i can't predict the string and use it like so prefix1\:div{color:#fff;}
xml file :
<?xml version="1.0" encoding="UTF-8"?>
<html xmlns:aa='zz' xmlns:ee='rr'>
<head>
<title></title>
<style type="text/css">
/* it work */ aa\:span{background: #00ff00;}
/* it doesnt work */ span{background: #00ff00;}
</style>
</head>
<body>
<div>
<aa:span id="span1">
<aa:p>aaa</aa:p>
</aa:span>
</div>
<div>
<ee:span id="span1">
<ee:p>aaa</ee:p>
</ee:span>
</div>
</body>
</html>
it's kinda weird because in the html render (browser) there's no more prefixes.
But, can you use a nasty trick like instead to build css on tag, you can build with ID.
Like :
// ninja coding =D
#span1{
color : black;
visible : hidden;
}
Maybe something interessant four you here

Summary of the problem
The following image is a description of bootstrap icon.
I don't know how to use "Code point".
Unicode: U+F120
CSS: \F120
JS: \uF120
HTML: 
For Using HTML code point, All you need is just set the the font-family of your element(or your body) to 'Bootstrap-icons' and then everything will work.
<!DOCTYPE html>
<html>
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap-icons#1.9.1/font/bootstrap-icons.css">
<style>
.test
{
font-family:'Bootstrap-icons';
}
</style>
<body>
<div class="test">

</div>
</body>
</html>
I managed to find how to use CSS of "code point".
Add following html into the head element of document.
Set font-family to be Bootstrap-icons.
And you can use css code point \F120 to fill the value of content property.
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap-icons#1.8.0/font/bootstrap-icons.css">
<style>
h3::before {
font-family:'Bootstrap-icons';
content:'\F120';
}
</style>
The otheres (Unicode, JS, HTML) are still ununderstood.
Thank you for reading my broken English! :)
I'm trying to include CSS in Phoenix templates (EEx) so that I can define components (that render on the server) that not only include HTML but also their own CSS. For that I would like to include a tag with the CSS for that template (component) hoping it would be injected in the <head> but that's not what happen. I made a few experiences and wasn't able to achieve that (weird enough when I did that my webpage didn't break and I could see <head> and <style> tags inside the <body>).
A sample templateXYZ.html.eex code could be:
<style>
.main {color: red;}
</style>
<div class="main">
<!-- Html code goes here -->
</div>
Note that the main goal of this is to allow me to write all the "component" code in one template (Html, CSS and Javascript - with the later there's no problem so I'm omitting it in the example/question) in a way that I only need to place the template in the proper place inside my other templates (rendering a template inside another template is also not a problem) and do nothing more (like as when I have a separated CSS file and need to import it in the <head>).
As a comparison, I can do what I want in the client side with raw Javascript that places my <style> and HTML in the DOM like this:
function f_auxButton(imgpath,id){
if (document.getElementById('auxButtonId')){} // <style> is only created on first component instanciation to avoid duplication
else {
$('<style id="auxButtonId">\
.auxButton {\
width: 25px;\
height: 25px;\
margin: 10px;\
}\
<\style>').appendTo("head")}
return '<img src="'+imgpath+'" class="auxButton" id="'+id+'">'
Then I just have to call <script>f_auxButton(arg1,arg2)</script> where I want to place the HMTL and I get it (plus the <style> tag that goes into the <head>.
So, is there a way of doing this?
app.html.eex
<!doctype html>
<html>
<head>
<title></title>
<%= render_existing view_module(#conn), "_styles.html", assigns %>
</head>
<body>
<div class="main">
<%= render_existing view_module(#conn), "_component.html", assigns %>
</div>
</body>
</html>
/web/templates/shared/_components.html.eex
<%= render MyApp.PageView, "_styles.html" %>
<img src="<%= static_path(MyApp.Endpoint, "/path/example.png")%>", class="auxButton">
/web/templates/page/_styles.html.eex
<style>
.auxButton {width: 25px;height: 25px;margin: 10px;}
</style>
Final Result
<!doctype html>
<html>
<head>
<title>My App</title>
<style>
.auxButton {width: 25px;height: 25px;margin: 10px;}
</style>
</head>
<body>
<div class="main">
<img src="/path/example.png" class="auxButton">
</div>
</body>
</html>
I'm doing something like this however, the word world won't appear. having that rule declare in the head css, it works fine.
can anyone explain this to me?
<span id="aa" style="#aa::after{content=" world";}">hello</span>
No. The style attribute only defines style properties for a given HTML element. Pseudo-classes are a member of the family of selectors, which don't occur in the attribute.
The style attribute doesn't accept selectors. It only accepts the rules to apply to the current element. You can't do this with a style attribute.
Working jsFiddle Demo
You must separate your CSS from your HTML:
<!doctype html>
<html>
<head>
<title>My Web Page</title>
<style>
#aa:after {
content: 'world';
}
</style>
</head>
<body>
<span id="aa">hello</span>
</body>
</html>
It's also better to create a file with .css extension, for example styles.css,
and put the style in it:
#aa:after {
content: 'world';
}
And in your HTML, link to this file:
<!doctype html>
<html>
<head>
<title>My Web Page</title>
<link rel="stylesheet" href="styles.css" />
</head>
<body>
<span id="aa">hello</span>
</body>
</html>
Be sure that your html and css file are in the same folder.
The style attribute applies styles to the current element; it cannot contain complete style sheet rules with selectors.
Although the selector in this case happens to match the same element, if it were possible, you would also be able to do this, which would make very little sense:
<div id="one" style="#two { display: none; }"></div>
... much content ...
<div id="two">Huh?</div>
Is it possible to inline a class definition of CSS inside an xhtml file?
I mean, to put someting like:
p.first{ color: blue; }
p.second{ color: red; }
Inside my page, not in a separate CSS file.
I think you're trying to put your CSS in the HTML page, not inline.
You can put CSS in an HTML page (usually in the head) by surrounding it in style tags:
<style type="text/css">
p.first{ color: blue; }
p.second{ color: red; }
</style>
Sure, here's an example. However, it is best practice to keep your styles in a separate css file.
<html>
<head>
<title>Classes</title>
<link rel="stylesheet" type="text/css" href="css/styles.css"/>
<style type="text/css">
img {
padding:10px;
margin:5px;
border:1px solid #d5d5d5;
}
div.thumb {
float:left;
}
div.caption {
padding-left:5px;
font-size:10px;
}
</style>
</head>
<body>
<div>your page code etc..</div>
</body>
</html>
You can also put css inside the p tag.
<html>
<body>
<p class="first" style="color:blue;"></p>
<p class="second" style="color:red;"></p>
</body>
</html>
The nice thing about CSS is it works in any file not just an HTML,XML file. You just need to define the syle block like this anywhere in the page
<style type="text/css">
<all my styles goes here>
</style>
In HTML and HTML/XHTML, the standard is, you will put this block in the head section. If it is other type of file for example .aspx, or .php, the block still works, even it is not in head block.
Example
<?php
/* mytest.php file */
<style>
<my styles>
</style>
?>
the same is true for ASPX file.
You can also define inline CSS which means CSS goes right in the element tag. The syntax is
<p style="<all my styles>"> My paragraph contain inline CSS</p>
Yes, you can insert CSS styles in the HTML file. For example:
<p>...</p>
<style type="text/css">
p.first { ... }
</style>
<div>...</div>
As you'll find in the literature, it's not considered a good practice though.
Is there a way to apply the ::selection and ::-moz-selection CSS pseudo-elements to the text inside a textarea?
textarea::selection {
color: #ff0000;
}
Isn't working
According to this, it should work.
Can you try giving it an !important?
Can you try applying it to a different element than a textarea, e.g. a div? If it works there, it works differently for input elements - but I can't find any resources mentioning that.
Updated as you said here, I'll update this question too:
I disagree. It is working ;)
Tested on Firefox 4.0b6
I can confirm the following code works at least under Firefox 4.0b6 (Taken from my own answer)
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>Test</title>
<style type="text/css">
p::-moz-selection, input::-moz-selection, textarea::-moz-selection {
color: red;
background-color: grey;
}
</style>
</head>
<body>
<p>This paragraph is selection-aware.</p>
<form action="#">
<input type="text" id="itext" value="So is this input[text]" />
<textarea id="itextarea">And this textarea, as well</textarea>
</form>
</body>
</html>
It may not be wroking programmatically, if you are not careful with what you are doing. Maybe you are trying to select something with jQuery.select() and you are selecting the textarea object instead of its content.
