Nobody asked, but in case you’re wondering, here are three excellent style guides you can find for free online:   

BBC News
Guardian / Observer
Telegraph

These are based around British English – for Americans, the best source is probably the AP Stylebook, or the New York Times style manual. Neither are available online, unfortunately, but you can buy them as those old-fashioned book things. 

The other good option, in my opinion, is the Chicago Manual of Style, which is available online but as a paid subscription (although with some free resources for teachers and students).
