No previous message | Next message →
Hi,
I'm learning web development, and as a totally blind screen reader user, it makes total sense to learn accessible web development as I learn, so I don't have to unlearn things. I was reading through the WCAG 2.0 Success Criteria and looking at CSS techniques. That's why I want to ask this. Should I always use em units and never use other units, or is it OK to use, for example, percentages also?
Thanks.
Jim

Just don't use px. Everything else will work fine.

We use em units for font-size and percentages for widths of containing elements. My understanding for ems on containers is that the width will grow as the text grows. So if you have a container and you want to maintain the text layout, then ems would be more appropriate. If screen layout is more important and you don't have a preference for when the text wraps to the next line, then using percentages for the container is more appropriate ... at least, that's my understanding.
I hope that makes sense!

Jim,
Generally speaking, they would both allow your UI to be liquid. This can help in resizing fonts on the screen. I would recommend using them. However, be careful how to apply them.

Ems and rems are the best path to follow for font sizes in my view. Rems
are useful as they avoid the crazy multiplications of fractions of ems on
fractions of ems.
