When you create a web page, browsers automatically apply their own default styles to HTML elements. These styles are sometimes helpful but can also cause inconsistencies if not handled properly.
Here are a few examples of how browsers style elements by default:
<h1>, <h2>, etc.)<h1> is bigger than <h2>).<h1>This is an H1 tag</h1>
<h2>This is an H2 tag</h2>
<p>)<p>This is the first paragraph.</p>
<p>This is the second paragraph.</p>
<ul> or <ol>)
