I have increased the width to 96%, cleared out my browser cache and it had no effect. The slide show that is used, is a plugin by Stefan Boonstra who answered above with the H1 tags.
In regard to the H1 tags, the only way I could remove the slideshow from the tag was to go into the home page and in the visual setting re-insert the slideshow making sure it was showing in paragraph format. The text portion did not show the HTML code, one thing that I am not used to not having access. Thus, my question regarding where I can find the HTML code for each page.
