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!

Subject: [WebAIM] Web Developer CSS Question

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
