Question about CMS blogs for iphone optimization

Whenever I hit a specific word count, the words on the blog article become so wide, that it extends past the page as if it were meant for the screen of two iphones next to each other. Why does it do this? how do i fix it?

For shorter articles it is fine, and doesn’t extend past the screen.

Some aspect of your design is telling the browser to restrict how it displays content. My guess would be to check for fixed or maximum height content wrappers that are preventing your layout from naturally expanding vertically.
