css
Copy code
@media (max-width: 600px) {
nav ul {
float: none;
display: flex;
flex-direction: column;
}
nav ul li {
width: 100%;
}
}
Enhancing User Experience with HTML5 and CSS3
Semantic HTML5
Using semantic HTML5 elements improves the readability of your code and the accessibility of your website. Elements like <header>, <footer>, <main>, <section>, and <article> help define the structure of your content clearly.
CSS3 Animations and Transitions
Animations and transitions can make your website more interactive and engaging. For instance, you can use CSS3 to animate the hover effect on buttons, providing a visual cue to users.
css
Copy code
button {
background-color: #4CAF50;
color: white;
border: none;
padding: 10px 20px;
text-align: center;
text-decoration: none;
display: inline-block;
font-size: 16px;
transition: background-color 0.3s;
}
button:hover {
background-color: #45a049;
}

The true power of web development lies in the integration of HTML5 and CSS3. By combining HTML5's robust structure with CSS3's styling capabilities, you can create stunning, responsive websites that stand out.
Multimedia in HTML5
HTML5 makes it easy to include multimedia elements directly in your web pages. For example, you can add audio and video without the need for external plugins.
html
Copy code
<video controls>
<source src="movie.mp4" type="video/mp4">
Your browser does not support the video tag.
</video>
<audio controls>
<source src="audio.mp3" type="audio/mpeg">
Your browser does not support the audio element.
