I'm a bit new can anyone help

Ok I just wrote out THE longest post resting on the subject of self promotion. Becoming an LLC and how to gain a contract to do live art as an LLC artist. And part of the post reads normal while the other half is side to side to view and read. What did I do wrong? I am a newb. So if this is normal then please ignore. I just wonder if it's the same for others viewing it. Or how can avoid this happening again? I have been doing most blogging via cell phone which is tablet size. But not sure if it's what caused it to turn out like that. Thanks in advance
