#+title: CSS failings #&summary A travel through my past Cascading Style Sheets mistakes #& #+license: wtfpl * CSS failings Once, I did not know about Cascading Style Sheets, or CSS. I knew HTML... What else would there be to know? Oh, and I knew the =font= tag. It's safe to say my websites were not optimal. ** px in font-size First, my apologies for not using the em&emph unit in font-size attributes. For years I have consistently used the px&emph unit when setting the sizes of fonts. I recently found out how wrong this is, how an incredibly arrogant offense to the universe it is, and I have begun correcting this mistake. Why is it wrong, you ask? I once thought about that, because I had read somewhere that it was best to use em&emph. But I didn't fully understand the unit, and I certainly didn't want my precious design to be viewed differently by different users! I wanted to force every user to view the exact same render of my pages. This was not ill-meant; I think it originated because of general browser incompabilities and was then taken to an unfortunate extreme. Essentially, it's wrong because it {forces the user to view the text in a specific size}&emph. If I had read that earlier on, I wouldn't have made so many px-based CSS's.
