html - Can I use a :before or :after pseudo-element on an input field?

Tuesday, June 26, 2018

I am trying to use the :after CSS pseudo-element on an input field, but it does not work. If I use it with a span, it works OK.

This works (puts the smiley after "buu!" and before "some more")

buuu!a some more

This does not work - it only colors someValue in red, but there is no smiley.

What am I doing wrong? should I use another pseudo-selector?

Note: I cannot add a span around my input, because it is being generated by a third-party control.

Answer

:after and :before are not supported in Internet Explorer 7 and under, on any elements.

It's also not meant to be used on replaced elements such as form elements (inputs) and image elements.

In other words it's impossible with pure CSS.

However if using jquery you can use

$(".mystyle").after("add your smiley here");

To append your content with javascript. This will work across all browsers.
