Provide additional font sizes
With responsive site, showing up on a full range of screen sizes, there are times that 12 pt text seems to large while 10 pt seems too small. My idea is to add odd numbered fonts like 9, 11, and 13. I'd also ask, that smaller sized fonts below 8pt be added as many times they are used to format certain columns, rows, and cells in tables. That extra flexibility can help save a lot of time going back into HTML (which I know nothing about) and trying to locate the area affected and then change each and every font size to the one I think I want- doing this over and over again until I get the look I was hoping for, or getting disgusted with all the wasted time and call tech support.

Font sizes shouldn’t be modified to that degree for most use cases and global changes should be handled in the CSS. It is recommended you contact support to help you with this.
We do believe however our new content editor for version 2 will offer this.

I would recommend submitting a ticket or contacting support about what you're trying to do exactly, just to make sure you're converting the page properly. Generally when using our responsive sites, you should not set any font sizes and only use default fonts, or remove assigned font sizes.
Also, tables should not be used when creating responsive content, so you should not be using rows, columns and cells, because they do not appear correctly when viewed on a mobile phone for example.
