Courses Plus Student 4,212 PointsCSS Deep Dive Struggle
I am struggling to pass this challenge after Relative Length Units video in CSS deep dive (in absolute length units):
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.
any suggestions??
I am not 100% on how to write the link with the class more ... I was thinking
.a class="more" {
font-size: 1.5rem;
}
I am also not 100% sure of what the base font size is.
I am using safari ... I know the rem unit is not acknowledged by all browsers.
Any help with where my error is??
Thank you!

3,530 PointsThe base font size of HTML is 16px - you are told this on the first part of the quiz. So basically all you have to write is this:
.more { font-size: 1rem; }
This will select the more class of the link and set the font size to the roots base size of 16px.

1,675 PointsWhy isn't it...
.more a { font-size: 1rem; }
I kept getting it wrong until I changed it to your answer above.

2,781 PointsI had the same question as Linda, technically you would want to select the class and the type of element to ensure it doesn't affect other things on the page
