Trouble with Select the link with the class more. Using the rem unit, set its font size back to the base font size of the root HTML element.

I am having trouble getting the CSS for this lesson. Can you send me the answer? Thanks!

Hi Stefanie,

You use rem and em to modify font size based on the root font size. The root font size is the default font size of the web page. If this size isn't explicitly declared by the person writing the code it will be supplied by the browser (typically 16px). If you declare a font-size of 2em or 2rem for an element the font size will be 32px (based on a root font size of 16px). So if you want to set a font to the root font size you would multiply the em or rem by 1: font-size: 1rem;

You need to select the link with the class more. Such as, .more { font-size: 1rem: }
