How to use CSS hover inside html-tag? [duplicate]

This question already has answers here: How can I write 'a:hover' in inline CSS? (26 answers) 开发者_如何学C Closed 5 years ago.

I want to do something like this:

<li style="hover:background-color:#006db9;">

But it wont work. Is this possible to do in some way, or do I have to write the css in the head or external css-document?

It is not possible with inline styles, but the (in)famous onmouseover / onmouseout event handler can do the same thing.

<li onmouseover="this.style.backgroundColor='#006db9'" onmouseout="this.style.backgroundColor=''">

Caveat: CSS definitions with hyphens have to be translated to Javascript using camelCase, like (css)background-color = (javascript)backgroundColor

This is not possible using the style attribute. You'll have to use CSS, either in the document itself or in an external file.

li:hover { background-color:#006db9; }

If that's not an option then you'll have to resort to JavaScript.

AFAIK this can't be done inline without Javascript. You will have to put it into the head or external stylesheets as you already suggest.

A <style> tag in the body is also interpreted by all browsers I know but is not valid and therefore not recommendable.

AFAIK You can't use pseudo-classes (:hover, :active, etc) on inline css.

Instead of just having the <li>, you can nest it in an anchors tag <a href="#" class="hoverable"> and then put this styling at the top of the file or in an external CSS file:

a.hoverable:hover{background-color:#006db9}

Or you can just use Javascript to avoid using the anchor tag.

I'd recommend JQuery.
