<h3>Other tips for HTML Beginners</h3>
<h4>1. Use a Modern Text Editor</h4>
<p>Tools like <a title="vs code homepage" href="https://code.visualstudio.com/" target="_blank" rel="noopener">Visual Studio Code (VS Code) </a>provide syntax highlighting, autocompletion, and other helpful features. VS Code also supports Emmet for faster HTML and CSS coding.</p>
<h4>2. Utilize Emmet</h4>
<p>Emmet is a plugin available in many text editors that allows you to write HTML and CSS more quickly. For example, typing <code>ul&gt;li*5</code> and then pressing 'Tab' will create a <code>&lt;ul&gt;</code> element with five <code>&lt;li&gt;</code> children as shown below:</p>
<pre class="language-markup"><code>&lt;ul&gt;
  &lt;li&gt;&lt;/li&gt;
  &lt;li&gt;&lt;/li&gt;
  &lt;li&gt;&lt;/li&gt;
  &lt;li&gt;&lt;/li&gt;
  &lt;li&gt;&lt;/li&gt;
&lt;/ul&gt;
</code></pre>
<h4>3. Indent Your Code</h4>
<p>Properly indenting your code makes it more readable. Most modern text editors offer automatic indentation.</p>
<h4>4. Always Close Tags</h4>
<p>Make sure to close all of your HTML tags. This helps to avoid unexpected rendering issues.</p>
<h4>5. Learn CSS and JavaScript</h4>
<p>Understanding CSS and JavaScript can help you create more dynamic and visually appealing websites. Consider studying them alongside HTML.</p>
<h4>6. Use Comments Wisely</h4>
<p>Comments can be helpful for leaving notes and reminders in your code, or for temporarily disabling a section of HTML.</p>
<h4>7. Practice Regularly</h4>
<p>Like any skill, practice makes perfect. Try building different types of web pages to improve your understanding and proficiency in HTML.</p>
<h4>8. Learn about Responsive Design</h4>
<p>Responsive design ensures that your website looks good on all devices. Learning about media queries and flexible grid layouts is essential for modern web development.</p>
