You can now add custom css to your theme and override our default styles. This will allow you to create completely unique styles that suit your companies branding and allow you to change components visually to optimise your conversation rate without having to wait for us to apply a new update.

[View our new demo](https://demo.signcustomiser.com/products/demo-custom-css) highlighting the customisation capabilities using CSS.

We have added unique class names for all components on our sign customiser app that will now remain for each new deploy. Previously it was not possible to add custom CSS styles to our sign customiser app as the classes would change for every new deploy. To get started please [read this article](/help/customise/custom-css/) as it goes through in detail how to add new styles and ensure they are preserved for each new deploy.
