The text in my article seem to be running off the screen in google chrome or internet explorer. 

Why Do i have this problem? İt is about formatting issue or something to do with internet browser? 
For example, in my computer when I open soledad theme demos, everything is well. But when i open my webpage, all page looks running off. Other wordpress themes and webpages are looking normal. I have this problem just on my webpage in the Soledad pencidesign theme.
Also, I took many complain about this running off problem.
