Highlight Invisible Bug

Hi. There is a strange error when I view my own site, and the error is evident on the live demo as well. Here are two screenshots.

On Chrome: http://i.imgur.com/zfFIxBR.png

Firefox: http://i.imgur.com/Xd40BTX.png

Viewing on android chrome seems to be fine.

Please help.

There also seems to be an issue with disqus, some code, “>, is evident on the main page when it says there have been comments.

Sometimes it shows that there has been a comment and it indicates that the number of comments with a superfluous “> at the end and other times even if there is a comment it says there are none and displays this in the alt text
