How do I change the font size of a tab?

Cascading Style Sheets (CSS) are an industry-standard way of styling a web page. The content of a page is rendered with HTML, and its look and feel are determined by CSS files.

You can upload a CSS text file, or type in a stylesheet, and apply it to a space or even a whole Confluence site.

Note: By default, only system administrators can edit the CSS for a space or for the site. To allow any user with Space Admin permissions to edit the CSS for a space, go to

→ General Configuration → Security Configuration and select Custom Stylesheets for Spaces.

There you can enter the following stylesheet to change the font size:

CSS

body div.aui-tabs>ul.tabs-menu>li.menu-item {    
   font-size: 30px !important;  
}
