Replace <h2 class="illus-h2"> with the <p> and <div class="illus-link"> <a href="#" target="_blank" class="link" title="Click here to Register"> with a button tag.
There is no need to give the body a max-width and min-height values.
Give the header, the main and the footer max-width:1440px; width:80%; margin: 0 auto;
for the right and left side space of the content.
There is no need to give the main a width and height value. give it a margin top and bottom values.
Use rem or em as unit for the padding, margin, width and preferably rem for the font-size for more on CSS units watch this https://youtu.be/N5wpD9Ov_To
