CSS: How to remove pseudo elements (after, before,...)?

Solution 1:

p:after {
   content: none;
}

none is the official value to set the content, if specified, to nothing.

Solution 2:

You need to add a css rule that removes the after content (through a class)..

An update due to some valid comments.

The more correct way to completely remove/disable the :after rule is to use

p.no-after:after{content:none;}

as Gillian Lo Wong answered.

Original answer

You need to add a css rule that removes the after content (through a class)..

p.no-after:after{content:"";}

and add that class to your p when you want to with this line

$('p').addClass('no-after'); // replace the p selector with what you need...

Solution 3:

$('p:after').css('display','none');

Solution 4:

As mentioned in Gillian's answer, assigning none to content solves the problem:

p::after {
   content: none;
}

Note that in CSS3, W3C recommended to use two colons (::) for pseudo-elements like ::before or ::after.

From the MDN web doc on Pseudo-elements:

Note: As a rule, double colons (::) should be used instead of a single colon (:). This distinguishes pseudo-classes from pseudo-elements. However, since this distinction was not present in older versions of the W3C spec, most browsers support both syntaxes for the sake of compatibility. Note that ::selection must always start with double colons (::).
