Is there a way to customize the appearance of JQuery UI tabs?

My current setup involves using JQuery 1.12 paired with JQuery UI (1.12). I am looking to customize the padding within specific tabs, but only on particular small mobile browsers. To achieve this, I have defined the following CSS:

@media only screen and (max-width: 400px) {
        .ui-tabs .ui-tabs-nav {
            margin: 0px;  
        }
        .ui-tabs .ui-tabs-nav .ui-tabs-anchor {
            padding: .5em .5em; 
        }
    }
    

Despite setting these styles in my code, when previewing my page on Mac Chrome's mobile browser emulator (essentially Mac Chrome), the default classes appear to be overriding my customized classes...

.ui-tabs .ui-tabs-nav .ui-tabs-anchor {
        float: left;
        padding: .5em 1em;
        text-decoration: none;
    }

    @media only screen and (max-width: 400px) {
        .ui-tabs .ui-tabs-nav .ui-tabs-anchor {
            padding: .5em .5em;
        }
    }
    

While attempting to integrate this into SO, I encountered challenges with copying the content accurately. There is a strikethrough line applied to "padding: .5em .5em;" within the media section, indicating an override has occurred. How can I ensure that my UI tab CSS definition takes precedence?

Answer №1

Avoid using !important as it is not recommended. A better approach to increase specificity in this scenario would be:

@media only screen and (max-width: 400px) {
    .ui-tabs ul.ui-tabs-nav {
        margin: 0px;  
    }
    .ui-tabs ul.ui-tabs-nav a.ui-tabs-anchor {
        padding: .5em .5em; 
    }
}

I am enhancing the specificity by using ul and a selectors. While others may refer you to official documentation, I want to emphasize that there are numerous ways to achieve this. Instead of my current approach, I could have also opted for something more general like adding an html or body selector at the beginning of each rule.

@media only screen and (max-width: 400px) {
    body .ui-tabs .ui-tabs-nav {
        margin: 0px;  
    }
    body .ui-tabs .ui-tabs-nav .ui-tabs-anchor {
        padding: .5em .5em; 
    }
}

Answer №2

To achieve this, you can use the following code snippet:

@media only screen and (max-width: 400px) {
   .ui-tabs .ui-tabs-nav {
     margin: 0px !important;  
   }
   .ui-tabs .ui-tabs-nav .ui-tabs-anchor {
     padding: .5em .5em !important; 
   }
}

Answer №3

Avoid using !important as it can make your code look messy and is generally not a recommended practice. Instead, consider the following approach:

@media only screen and (max-width: 400px) {
    .ui-tabs.ui-tabs ul.ui-tabs-nav {
        margin: 0px;  
    }
    .ui-tabs.ui-tabs ul.ui-tabs-nav a.ui-tabs-anchor {
        padding: .5em .5em; 
    }
}

By implementing this, you can enhance the priority of your css syntax in a more organized manner.
