      <p>HTML is the foundation of web content.</p>
      <p>It uses tags to structure text, images, and links.</p>
      <p>Each tag has an opening and closing form.</p>
      <p>Attributes add extra information to elements.</p>
      <p>HTML5 introduced semantic elements.</p>
      <code>&lt;div&gt;Content&lt;/div&gt;</code>
      <code>&lt;img src="image.jpg" alt="description"&gt;</code>
      <ul>

    <section class="main-section" id="CSS_Selectors">
      <header>CSS Selectors</header>
      <p>Selectors target HTML elements for styling.</p>
      <p>They can be simple or complex.</p>
      <p>Class selectors use a dot prefix.</p>
      <p>ID selectors use a hash prefix.</p>
      <p>Combinators define relationships.</p>
      <code>p { color: blue; }</code>
      <code>.box:hover { background: yellow; }</code>
      <ul>
        <li>Universal selector</li>
        <li>Descendant selector</li>

      </ul>

    <section class="main-section" id="Responsive_Design">
      <header>Responsive Design</header>
      <p>Responsive design adapts to screen sizes.</p>
      <p>Media queries are key tools.</p>
      <p>Flexible layouts use percentages.</p>
      <p>Images should scale with containers.</p>
      <p>Breakpoints define layout changes.</p>
      <code>@media (max-width: 600px) { ... }</code>
      <code>img { max-width: 100%; height: auto; }</code>
      <ul>

    <section class="main-section" id="Accessibility">
      <header>Accessibility</header>
      <p>Accessibility ensures content is usable by all.</p>
      <p>Use semantic HTML for screen readers.</p>
      <p>Provide alt text for images.</p>
      <p>Ensure sufficient color contrast.</p>
      <p>Use ARIA roles when needed.</p>
      <code>&lt;button aria-label="Close"&gt;</code>
      <code>&lt;nav role="navigation"&gt;</code>
      <ul>
        <li>Keyboard navigation</li>

    <section class="main-section" id="Semantic_HTML">
      <header>Semantic HTML</header>
      <p>Semantic elements describe their meaning.</p>
      <p>They improve accessibility and SEO.</p>
      <p>Examples include &lt;article&gt;, &lt;section&gt;, &lt;aside&gt;.</p>
      <p>Use them instead of generic &lt;div&gt; tags.</p>
      <p>They help organize content logically.</p>
      <code>&lt;main&gt;Main content&lt;/main&gt;</code>
      <code>&lt;footer&gt;Footer info&lt;/footer&gt;</code>
