CSS (Custom Style Sheets) is used to define styles for your web pages, including colours, fonts, layout and variations in a display for different devices and screen sizes.
Document360 provides a rich and elegant look for your site by default. It also allows you to change the site layout colour to your brand colour. If you would like to customize the site as per your requirements, you can add your own custom CSS to replace the default theme style.
Say, you want to insert a custom script into your site to do some specific function. Document360 will inject your script in the header section as external file and execute it with/without changing the theme.
