Basically do what was originally instructed, and then remove the codes in a few more spots.
1. Under PORTFOLIO THUMBNAIL HOVER
2. Under SHAPED STYLED ITEM
I would disregard line numbers as they will likely change as the theme is updated.
NOTE: By removing the URL to “(../images/sprite.png)”, you are removing the magnifying glass and link icons, which is what I wanted to achieve. You may have to play around a bit if you’d like those to remain.
