The new Research and Conferences template allows you to customise fonts (see the font picker) and change the colour scheme of your site (see the colour scheme picker).
If you have a little more web development technical knowledge you may wish to go even further and customise the CSS of your site; there’s a piece of “Custom CSS” content in the “Section Styles” section to let you do just that.
You should put your CSS inside a <style> tag as show below.
Once you have made your style changes, click “Update and Approve” then preview your site to see the changes.
