HTML (Hypertext Markup Language) is a markup language used to build web pages. It is the basis for building web pages. In this article, we'll cover how to write HTML and add style and functionality to your website.
- Writing HTML documents
HTML documents are composed of tags, and tags can be nested. Each tag has an opening tag and a closing tag, for example:
<html>
<head>
<title>这是网页标题</title>
</head>
<body>
<h1>欢迎来到我的网站</h1>
<p>这是一个段落</p>
</body>
</html>In this example, we have a root tag of HTML, a 93f0f5c25f18dab9d176bd4f6de5d30e tag that contains the title of the web page, and a 8292cc29bcdc564d0d880ecfa0a43ee2 tag, we have an 4a249f0d628e2318394fd9b75b4636b1 tag for the heading and a e388a4556c0f65e1904146cc1a846bee tag for the paragraph.
- Tags and attributes
HTML tags can have attributes to specify the characteristics of the tag. For example, the a1f02c36ba31691bcfe87b2722de723b tag can specify the URL of the image through the src attribute, as shown below:
<img src="https://example.com/image.jpg" alt="这是图像的描述">
In this example, we specify the URL of the image using the src attribute, and the alt attribute provides a description of the image.
- Links
In a web page, we can add links to other web pages or local files. Use the tag to create a link, for example:
<a href="https://example.com/">这是一个链接</a>
In this example, we use the href attribute to specify the URL of the link target.
- List
We can use lists to organize information. HTML has two types of lists: ordered lists and unordered lists. Ordered lists use the c34106e0b4e09414b63b2ea253ff83d6 tag, while unordered lists use the ff6d136ddc5fdfeffaf53ff6ee95f185 tag. For example:
<ol>
<li>第一项</li>
<li>第二项</li>
<li>第三项</li>
</ol>
<ul>
<li>第一项</li>
<li>第二项</li>
<li>第三项</li>
</ul>In this example, we use the c34106e0b4e09414b63b2ea253ff83d6 tag to create an ordered list, and the ff6d136ddc5fdfeffaf53ff6ee95f185 tag to create an unordered list.
- Style
We can use CSS (Cascading Style Sheets) to add styles to the website. CSS is a style sheet language used to describe the appearance and layout of web pages. For example:
<!DOCTYPE html>
<html>
<head>
<title>这是网页标题</title>
<style>
h1 {
color: red;
font-size: 48px;
}
p {
font-size: 24px;
line-height: 1.5;
}
</style>
</head>
<body>
<h1>欢迎来到我的网站</h1>
<p>这是一个段落</p>
</body>
</html>In this example, we embed the c9ccee2e6ea535a969eb3f532ad9fe89 tag within the 93f0f5c25f18dab9d176bd4f6de5d30e tag to add styles. We use the h1 selector to select the page title and specify the color and font size. We use the p selector to select paragraphs and specify font size and line height.
- JavaScript
We can use JavaScript to add interactive and dynamic features to our website. JavaScript is a scripting language that can be used with HTML and CSS. For example:
<!DOCTYPE html>
<html>
<head>
<title>这是网页标题</title>
</head>
<body>
<h1>欢迎来到我的网站</h1>
<button onclick="alert('你点击了按钮')">点击我</button>
</body>
</html>In this example, we create a button using the bb9345e55eb71822850ff156dfde57c8 tag and add JavaScript code in the onclick attribute to pop up an alert box when the button is clicked.
Summary
In this article, we introduced the basics of HTML, including writing HTML documents, tags and attributes, links, lists, styles, and JavaScript. With these basics, you can start building simple websites and applications. However, keep in mind that if you want to build a high-quality and maintainable website, you need to learn these basics in depth and move on to advanced topics like object-oriented programming, frameworks, and libraries.
