On some sites, when I go to certain pages, all the linkable text is bright red. And all clicked links turn a darker red. I've searched about Google and found about this 'error' in Safari. link for article Now, Im pretty good with computers, but I dont understand what a CSS document is, or anything about HTML (which, from what I understand, seems to be the problem.) Can someone explain what a CSS is, and how I might go about fixing this? Safari is my favorite browser, so I would reall not want to switch to a new one because of this.
