Thanks for writing in!
As far as making the font look better on the right side above it, the font should be a little larger.
Please add the following code under your Theme Options -> Custom CSS
font-size: 23px !important;
If you wish to justify the ‘Popular Articles’ text (see: http://prntscr.com/9t3ux6); you can use the above code, otherwise remove the “margin-left: 18px;” from the provided code.
