Legibility on small devices could be improved

[roobie]

Greetings

Today I visited CLiki.net with my mobile phone, and found that i could not read the contents of the site, due to the text being very small. To fix this, one might add the viewport meta-tag in the header of the document, as described on the MDN site

I'll try to take a look at creating a PR doing this within a couple of days.
