How to override css containing '!important' using jquery?

Question

I want to apply height for specific div using jquery but not able to override the \'!important\' keyword using jquery.

Here is

Answer 1

First Id is unique identifier, therefore you don't need to search div by it's class name. therefore you can filter div by it's id.

Try following code

first add new Class property below myClass like this

it will override height property of myClass

now just add this class to div

$('#divL3').addClass('testClass');

but making height "0" wont hide content of "divL3". you rather try to hide overflow content or hide entire div by adding css property display:none

hope it will work for you.
