The challenge descriptions above have links with with font-size smaller than the rest of the content.

@raisedadead I wanna take it or prep it for first timers. Your call.
This probably going to be the case for every challenge, basing on the same template. I think if you are Ok, you should take this up.
Not sure if this information is useful, or even accurate, but I think that the anchor tags have their sizes set here...
And I think the rest of the text gets its size set here
EDIT: classes > elements so the a selector will have less say in the font-size than the .step-description will. Thus, assuming everything I've said above is true (and there's no guarantee of that!), then I guess the best thing to do is to add
.step-description a {
font-size: 1.5em;
}
I'm not too sure. Good luck solving the issue!
@joker314 Thanks j. I just changed .@{ns}-description a { font-size: from your comment to 1em since the size is relative to its parent which is .@{ns}-description. BTW, how did you find the files so quickly?
@ahmadabdolsaheb Yay!
I first opened my developer console and took a look at the styles for the links and the normal text. I saw this:

and

I then thought that maybe the grey link in the top right of both images would be a file name which contained both of those selectors. Alas, it wasn't! I would later discover those were two seperate files that would be combined.
So, what next? Well, I tried searching for the .step-description selector in the GitHub search bar. Alas, there were no results (this was actually quite surprising to me). Of course, this was because the selector was actually .@{ns}-description.
I then decided to search for font-size: 1.5em in the GitHub search bar. There were six results; and when I excluded JSON results, I got just two. One of them was a comment, and the other one had it's class name end in -decription! That was one file found.
I then tried the same technique for the a selector. I searched for font-size: 15px. There were a lot of results, though, and while I could've just looked through them to find font-weight: bold; on the previous line of the matched term; I instead just prepended it in the search bar. The top result had them one after the other, all inside an a selector! Yay, I'd found the second one!
Hope this explains it!
@joker314 it does. thanks for sharing your thought process.
