Is it possible in CSS/HTML to generate new elements without the need for Javascript? This way, I could import a CSS or HTML file and load a new element to replace existing code like this:
<html>
<body>
<div id="titlebar" style="background-color:#ff0000;">
<label style="color:#00ff00;">This is a title</label>
</div>
</body>
</html>
by using something more concise like this or a similar shorthand (e.g. class="titlebar"):
<html>
<body>
<titlebar>
This is a title
</titlebar>
</body>
</html>
If you're not sure what I mean, feel free to ask below.
