I am very new to the field of network coding and need some help. I'm making a web page for a local sports team and since their web page doesn't look that great and Wordpress isn't very user-friendly, I thought it might be easier to try coding it myself.

I can't enter the navigation bar, main content, and footer on the page. I want the navigation bar, main content, and footer to be entered and only 80% wide so you see some background with pictures of athletes from sports teams)

#footerWrapper { max-width: 80%; max-height: 5%; margin-bottom: 20px; line-height: 30px; font-size: 0.9em; border: 0 solid #ddd; border-bottom-color: #3F8444; border-width: 1px 0;} /*Positions and Margins*/ .image { position: absolute; top:100px; left:100px; } .image-1 { position: absolute; top:20px; right: 100px; } header{ text-align: center; margin-top: 100px; margin-bottom: 100px; } main{ width: 80%; display: flex; flex-direction: row; justify-content: space-evenly; align-items: center;} footer{ position: static; left: 0; bottom: 0; width: 80%; height: 5%;} p {margin-left: 5px; margin-right: 5px;} /*Navigation*/ ul { display: flex; flex-direction: row; align-items: center; list-style-type: none; margin: 0; padding: 0; overflow: hidden; background-color: #04AA6D; width: 80%; } /*li {float: left;}*/ li a, .dropdown li a { display: block; color: white; text-align: center; padding: 14px 16px; text-decoration: none; } li a:hover, .dropdown:hover .dropbtn {background-color: #111;} li.dropdown { display: inline-block;} .dropdown-content { display:none; position: absolute; background-color: #04AA6D; color: white; min-width: 160px; box-shadow: 0px 8px 16px 0px rgba(0,0,0,0,.2); z-index: 1; } .dropdown-content a { color: white; padding: 12px 16px; text-decoration: none; display: block; text-align: left; } .dropdown-content a:hover {background-color: #111;color: white;} .dropdown:hover .dropdown-content { display: block; }
