Guildi offers many templates that you can customize via themes.
In addition to the themes, you can customize the basic design in several ways depending on the degree of customization you want and the time you want to spend on it.
Quick customisation allows you to change the colours, fonts and background of the whole site in a few minutes and without any technical knowledge.
Advanced customisation allows you to change colours, fonts and dimensions on an element-by-element basis.
This gives you almost total control over the appearance of your guild site.
CSS customisation is for experienced users with knowledge of CSS.
It allows you to write the code you want.
