What is Semantic Tag
Semantic tag means - Semantic tags, i.e. tags that tell browsers and developers what is the actual meaning of a content.
Non-semantic tags (like `<div>` `<span>`) only provide structure but do not tell what the content is being used for. Whereas semantic tag makes the purpose of the content clear.
Simple example of semantic tag:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>My Website</title>
<style>
body {
font-family: Arial, sans-serif;
margin: 0;
padding: 0;
}
header,
main,
footer {
padding: 20px;
}
header {
background-color: #f4f4f4;
font-size: 24px;
font-weight: bold;
}
main {
background-color: #fff;
min-height: 300px;
}
footer {
background-color: #f4f4f4;
font-size: 14px;
}
</style>
</head>
<body>
<header>My website</header>
<main>
Here will be the main content
</main>
<footer>
Contact us: <a href="mailto:info@example.com">info@example.com</a>
</footer>
</body>
</html>
Here `<header>`, `<main>` and `<footer>` tags clearly tell which section is for what purpose. These help in readability, SEO and code maintenance.
Why and how are semantic tags used:
Why are they used:
1. Easy to understand code: Developers can immediately understand what the section is for.
2. SEO friendly: Helps search engines understand the structure of the page.
3. Accessibility: Helps screen readers understand the content.
4. Future proof code: Since it is an HTML5 feature, modern browsers support it better.
How are they used:
You write semantic tags in the same way as normal HTML tags. They are just named according to their function.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>My Website</title>
<style>
body {
font-family: Arial, sans-serif;
margin: 0;
padding: 0;
line-height: 1.6;
}
header,
main,
footer,
article {
padding: 20px;
}
header {
background-color: #f4f4f4;
font-size: 24px;
font-weight: bold;
}
main {
background-color: #fff;
}
footer {
background-color: #f4f4f4;
font-size: 14px;
}
article {
background-color: #eef;
margin-top: 20px;
border-left: 4px solid #88c;
}
h2 {
margin-top: 0;
}
</style>
</head>
<body>
<header>My Website</header>
<main>
