A question about a:hover_html/css_WEB-ITnose

If
a:hover {color: #FF00FF}
is defined in the css tag, then when we move the mouse over the link, the link will change color.

But now the situation is a bit special and requires that css tags cannot be defined and css files cannot be imported.
How can I implement this function? Is it okay if we just do ? How to write?

<a href="http://www.baidu.com" onMouseOver="javascript:this.style.color='#FF0000';" onMouseOut="javascript:this.style.color='#0000FF';"> TEST color change </a>

Can it be implemented using css?

Pseudo-classes cannot be written here

Just tested it OnMouseOver and onMouseOut are also filtered out.
Can you write

like this? Write the pseudo class in the style of the div?

With JS disabled, what else can you do online?

How to filter out all

Is there anything else that can be used?

Don’t think about it, it can’t be done unless the platform opens up independent CSS

This is the case on Taobao. It is impossible for ordinary users to change text color through code. They have to use templates specified by the platform
