Customize pfsense interface
Can anyone help me how to change web interface?
you need more details question is far tooooo broad
I believe most of the web interface can be changed through editing the CSS files for the various themes. Make a copy of one of the files (they're in /usr/local/www/css) then edit the copy as much as you want. When you're done, go to the Themes setting (it's on the System > General page) and select your new custom theme.
