Remove absolute positioning from UI examples where possible

[ickshonpe]

What problem does this solve or what need does it fill?

Absolute positioning is straightforward and easy to understand. However, many users struggle with using the other style properties correctly. Providing more examples of their use could help users better understand these properties.

What solution would you like?

Instead of using absolute positions, use combinations of the other style properties to achieve the same effect.

#6743 doesn't fix any bug related to positioning, so it shouldn't change anything?

Also, absolute positioning is not something bad in itself, why would you want to get rid of it?

I dunno, there are fixes for bugs that affect the layout which affect positions etc. Anyway rewrote the issue, it was written badly, I shouldn't have included that part.

Yes it's not bad or anything, but it's less flexible and portable etc so shouldn't be encouraging people to use it unless they have to.
