          <p>
            All modern websites and web applications are built using three
            <em>fundamental</em>
            technologies: HTML, CSS and JavaScript. These are the languages of
            the web.
          </p>

          <p>
            In this post, let's focus on HTML. We will learn what HTML is all
            about, and why you too should learn it.
          </p>

          <h3>What is HTML?</h3>
          <p>
            HTML stands for <strong>H</strong>yper<strong>T</strong>ext
            <strong>M</strong>arkup <strong>L</strong>anguage. It's a markup
            language that web developers use to structure and describe the
            content of a webpage (not a programming language).
          </p>
          <p>
            HTML consists of elements that describe different types of content:
            paragraphs, links, headings, images, video, etc. Web browsers
            understand HTML and render HTML code as websites.
          </p>
          <p>In HTML, each element is made up of 3 parts:</p>

          <ol>
            <li class="first-li">The opening tag</li>
            <li>The closing tag</li>
            <li>The actual element</li>
          </ol>

          <p>
            You can learn more at
            <a
              href="https://developer.mozilla.org/en-US/docs/Web/HTML"
              target="_blank"
              >MDN Web Docs</a
            >.
          </p>

          <h3>Why should you learn HTML?</h3>

          <p>
            There are countless reasons for learning the fundamental language of
            the web. Here are 5 of them:
          </p>

          <ul>
            <li class="first-li">
              To be able to use the fundamental web dev language
            </li>
            <li>
              To hand-craft beautiful websites instead of relying on tools like
              Worpress or Wix
            </li>
            <li>To build web applications</li>
            <li>To impress friends</li>
            <li>To have fun 😃</li>
          </ul>

          <p>Hopefully you learned something new here. See you next time!</p>
