When I was new to blogging. I always find my posts after publishing with highlight marks. I did not know how to remove and even Google for it to find solution. But I can't find any tutorials so I just let it be. Then after a year of blogging I figured out how to solve this problem.
Removing the highlight is so easy and I know that some bloggers are still having problem with this. Here is the three simple steps that should be done to have good looking post.
1. Highlight the part of the post that needs correction.
2. Then click on the "REMOVE FORMATTING" icon.
3. Click on " PREVIEW" to check.
When you're done. Check the "TEXT BACKGROUND COLOR" and it should look like this.
Make sure to use the "PREVIEW" always before publishing your post.
