Centering and positioning objects on CSS can be tricky, but there are a few tips that can help:

To center an element horizontally, you can use the margin: 0 auto; property on the element's container. To center an element vertically, you can use the display: flex; and align-items: center; properties on the element's container, or use the position: absolute; and top: 50%; properties on the element itself.

In order to fix the accessibility issues:

• You need to replace <div class="rectangle"> with the <main class="rectangle"> tag. You'd better use Semantic HTML, and you can also reach more information about it from Using Semantic HTML Tags Correctly.
• Each main content needs to start with an h1 element. Your accessibility report states page should contain a level-one heading. So, you should use one <h1> element in the <main> tag. You can replace your <h2>Improve your front-end skills by building projects</h2> element with the <h1>Improve your front-end skills by building projects</h1> element.
