I'm making a new page and all the hyperlinks in the body text are highlighting for some reason. Any idea why? 

Do you use custom css for the page or just the editor?

My only assumption would be that when choosing a hyperlink colour with not enough contrast to the background, it may auto-highlight it. So you could try choosing a different colour combination.

It seems like it's stuck like that no matter which color I pick, and even when I remove my custom CSS (which I'll include below just to be thorough).

.right_col.column {
visibility: hidden;
height: 0px;
}
.wrapper { background-position: bottom;}
.responsive .inner_column { max-width: 500px; padding-right: 3%; padding-left: 3%; padding-top: 3%}
.header.has_image img {
    display: inline-block;
    max-width: 93%;

Update: I deleted the link, then added it back in and it now it looks fine! Don't know why I didn't try that before anything else lol. Anyways, thanks for your help!
