Building for application accessibility legal requirements (in the UK specifically)

Been looking at accessibility requirements for a build in the UK.  Been working through the guidance in this document

One of the things we have been looking at is 'em' and 'rem' for font size. In the current build Font only supports Pixels.  Does anyone have a robust approach using CSS etc?  

You can define a style class to use different typography sizing. This is my go to site for when I need to remember how to do this.

Hi Sam,

Is the extension of this suggestion that you setup the CSS style classes in a theme as EM or REM to capture most common cases?


Thanks
