Red Highlight showing up on anchor close for Twitter, on Facebook beginning and end, and code following it.

While in the middle of this lesson I noticed The red highlight, which comes up in workspaces while adding and modifying code, is showing up where it shouldn't since the code appears to be correct. The highlight starts after the closing quotation mark for Logo on the code for Twitter and ends after the anchor close. On Facebook it starts at the anchor open, covers href, equals sign, opening quote, and the same part of as it does following Logo for Twitter. It then covers the rest of my code at the end. The following screenshot shows what I'm trying to descibe: http://imgur.com/8m3ao70 What am I doing wrong here and how do I fix this issue?
