So this might be really simple, but I haven\'t been able to find any examples to learn off of yet, so please bear with me. ;)
Here\'s basically what I want to do:>

You could wrap the 'content div' with an 'outer div' which is set to an absolute width value. Inject the new content with a "hide()" or "animate({width})" method, shown in the other answers. This way, the page doesn't reflow in between because the wrapper div holds a steady width.
