You will need to [inspect](https://developer.mozilla.org/en-US/docs/Tools/Add-ons/DOM_Inspector/Introduction_to_DOM_Inspector) the CSS on the browser and amend it, applying your customisations to a Theme or Theme Component.

This is the realm of Theme development.

Take a look at [Beginner's guide to using Discourse Themes](https://meta.discourse.org/t/beginners-guide-to-using-discourse-themes/91966) to help you with the Discourse specifics.

However, this is largely a general web development technique which is not the focus of this forum.

You might want to take a look at some guides like [CSS Tutorial](https://www.w3schools.com/Css/) or [CSS styling basics - Learn web development | MDN](https://developer.mozilla.org/en-US/docs/Learn/CSS/First_steps)
