It's happened to almost all of the websites. Even Google. It's really annoying because I can't see anything and I need to revise please help asap. I've tried holding 'ctrl' and pressing '+' and holding 'ctrl' and using the sroll button on the mouse. I've even tried going on 'setting' and clicking the plus to make it bigger but it's no use. Thanks. Five star rate for the first answer that works!
