There‚Äôs an unsightly and extraneous post navigation in the Creative theme by Modern Themes. The culprit can be found on line #16 to line #37. Sometimes, it can be so easy to just remove the offending lines of code but other times, you may want to keep them intact and just hide their presentation some other way. In this case, I “remove” the post navigation by hiding their display using CSS.

Here’s the original file that I couldn’t touch. Reviewing the file enabled me to see what selector to use for the CSS. Of course I could also have done this using Chrome browser’s inspect functionality but where’s the fun in that!?!?!?!
