# Custom CSS

### What is the Custom CSS feature and how do I use it?

The Custom CSS feature is an incredibly useful tool. This gives you the ability to change any aspect of your design, from the size of your images to the color of a single word of text.

We only recommend you use this if you have sufficient knowledge of this design feature. Not to worry if you don't, if you have this feature available to you, simply get in touch with our friendly support team and a designer will be more than happy to inject CSS to implement the changes you ask for.
