Thanks! I just realised my mistake! I thought the default maximum width was 600px. Is it possible to increase the width of the blog page itself at all using CSS? Apologies for any inconvenience and thanks very much again for your help.
Thank you very much! The borders have now disappeared.
I'd like to increase the size of the images in each blog post. For example, in this post the images are 600px across but I'd like them to be around 800px if possible.
