To create a well-structured and visually appealing HTML page, you'll want to use a combination of HTML for the structure and CSS for styling. Here’s a detailed guide on how to achieve this:

1. Creating a Hierarchy with HTML

Headings and Sections

HTML headings (<h1>, <h2>, etc.) define the hierarchy of your content. Use these to create a clear structure.

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document Title</title>
    <link rel="stylesheet" href="styles.css">
</head>
<body>
    <header>
        <h1>Main Heading</h1>
    </header>
    <section>
        <h2>Section Heading</h2>
        <p>This is a paragraph within a section.</p>
        <p>Another paragraph in the same section.</p>
        <hr> <!-- Horizontal rule to separate content -->
        <h3>Subsection Heading</h3>
        <p>This is a paragraph within a subsection.</p>
    </section>
    <footer>
        <p>Footer content here.</p>
    </footer>
</body>
</html>

2. Using Paragraphs and Line Breaks

Paragraphs

Use the <p> element for paragraphs. It automatically adds space before and after the text, which helps in readability.

<p>This is a paragraph of text. It is automatically spaced from other paragraphs.</p>
<p>Another paragraph of text. Each paragraph is treated as a separate block-level element.</p>

Line Breaks

Use the <br> tag to insert a line break within a paragraph or other inline text.

<p>This is a line of text.<br>And this text appears on the next line.</p>

3. Dividing Sections with a Horizontal Line

Use the <hr> element to create a horizontal line that separates sections of your content.

<section>
    <h2>First Section</h2>
    <p>This is some content in the first section.</p>
    <hr>
    <h2>Second Section</h2>
    <p>This is some content in the second section.</p>
</section>

4. Formatting Text with CSS

Inline CSS

You can use inline CSS directly in your HTML elements for quick styling.

<p style="color: blue; font-size: 18px;">This is a blue colored text with a font size of 18px.</p>

Internal CSS
