If you are using a responsive skin it is important that you not simply place html from another site into your product descriptions and other areas. Other sites may use different code that will not work with the responsive skin. When the two are combined the site will still adjust but the content from the other site will stay at a fixed size. This causes the content to overlap and look incorrect. The best way to handle this is to either create the content directly in Pressero or only place in the plain text and then format it to your liking with the Pressero editor.
