Pseudo classes (like :hover) never refer to an element, but to any element that satisfies the conditions of the stylesheet rule. You need to edit the stylesheet rule, append a new rule, or add a new stylesheet that includes the new :hover rule.
I need to find a way to change CSS :hover properties using JavaScript.
For example, suppose I have this HTML code:
<table>
<tr>
<td>Hover 1</td>
<td>Hover 2</td>
</tr>
</table>And the following CSS code:
table td:hover {
background:#ff0000;
}I would like to use JavaScript to change the <td> hover properties to, say, background:#00ff00. know I could access the style background property using JavaScript as:
document.getElementsByTagName("td").style.background="#00ff00";But I don‘t know of a JavaScript equivalent for :hover. How do I change these <td>‘s :hover background using JavaScript?

Pseudo classes (like |
var css = ‘table td:hover{ padding: 0px; border: 0px; color: rgb(48, 51, 54);">;
style = document.createElement(‘style‘);
if (style.styleSheet) {
style.styleSheet.cssText = css;
} else {
style.appendChild(document.createTextNode(css));
}
document.getElementsByTagName(‘head‘)[0].appendChild(style);Change :hover CSS properties with JavaScript
