It’s because you wrapped all of your code in a hyperlink. You also didn’t properly close out your tags.
Example, this is what you have –
<h4>This title is wrapped inside h4 tags</h4>
<p>This content is wrapped inside the "p" tag. Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.</p>
Notice there is no end tag for the hyperlink, and you put it before the h4 title and “p” content. The end tag should look like this – </a> and you should only add the <a href="your-link.com"> before your link and the </a> end tag right after.
