In addition to the values containing numbers, the font-size property can have one of the following values as well: medium|xx-small|x-small|small|large|x-large|xx-large|smaller|larger|initial|inherit; At this point, HtmlFormatProvider skips these values and applies default font-size to the content. To import similar content with the proper styling, the customer can replace the CSS keywords with their equivalents in px.
