How can I disable highlighting in html or JS?

Question

I need to disable the highlighting of selected text on my web app. I have a good reason for doing this and know that this is generally a bad idea. But I need to do it anyway

Answer 1

You can use the CSS pseudo class selector ::selection and ::-moz-selection for Firefox.

For example:

::-moz-selection {
    background-color: transparent;
    color: #000;
}

::selection {
    background-color: transparent;
    color: #000;
}

.myclass::-moz-selection,
.myclass::selection { ... }
