After a couple of web developers failed me on creating the website my business needed I took a course on UDEMY, used a bootstrap template, and made my own.  That was a couple of years ago.  Yesterday I found that a link was broken and when I went to repair it I broke the code somewhere else.  I have fixed almost everything but I'm still having one problem;the banner on the carousel isn't spanning the full page (it does span the full page for mobile or medium browser size just not full size).

The website is www.POOL-ology.com.  Can someone please take a look at the html and see if they notice anything wrong?  If I need to attach the html files please let me know!

Thank you in advance for the help!
