So far I added more red lines to separate the website. It is starting to look like a normal website now. The main colour will be red and the background is going to stay white. The writing will be in either dark blue or in black when I want to separate little pieces of information.
I am going to use dark colours for writing because making it colourful would not make it look serious, which would be not good, because it's not how I want this website to look like - it wouldn't suit the purpose of it.
