Edit css to work in all browsers

Very quick project - a small section of CSS works as intended in Firefox 40. Doesn't work correctly in IE, Chrome, Safari, or Opera. Please fix the CSS to work in all browsers like it does in Firefox 40. There are 2 different layouts as you change browser width: 1) width greater than 949px, and 2) width less than 949px. Here is the file: [login to view URL] Update the stylesheet in styles/[login to view URL] in the /* Features, Samples */ section starting at line 70, and the @media (max-width: 949px) section starting at line 304, namely lines 353-355. If it is necessary to change the html too, that is ok. Don't worry about the links. This project is to only fix the look of the layout in 2 different browser widths to be consistent across browsers. You don't need access to my server. Please post results on your own server or simply send back the code. I'd like this done in the next 12 hours if possible. Thanks-
