I like to share a bit about what I've learned during working with this blog. Of course it is also a memory for myself, when I'm too lazy to take notes or when I can't find them.
I needed those tags when I wrote the side element about language stuff.
If adding a html-tag you first have to change to "edit Html".
<> gives you a break of lines
< href = "http://link"> Name of the link < /a > This way you can insert a link.
IMPORTANT: You have to remove all spaces before and after the little sideway triangles <> and before and after the = .
