How to remove and override CSS attribute from parent class?

Tags: html,css,twitter-bootstrap

Problem :

I have a file bootstrap.min.css which has the following class

.nav-tabs {
    border-bottom: 1px solid #ddd;

I created a new css nav-tabs.css which has

.nav-tabs {

How do I remove the font-size from parent if the requirements change in the future?

Solution :

Don't use !important unless you really, really have to.

You can change the font size in this case by either adding the new css after the old like so:

.nav-tabs {
    border-bottom: 1px solid #ddd;
    font-size:14px; /*old*/
.nav-tabs {
    font-size:18px; /*new*/

Likewise using two style sheets the same will apply:

<link href="/bootstrap.css" rel="stylesheet"> //old
<link href="/Your_Custom_CSS.css" rel="stylesheet"> //new

or probably preferably by being a little more specific in the selector like so:

.nav-tabs { /*less specific*/
    border-bottom: 1px solid #ddd;
.nav-tabs li { /*more specific, li is just an example*/
