HTML and CSS languages are the cornerstones of building modern websites. The two are closely related and work together. In this article, we’ll explore how to write HTML and CSS, and how you can use them to build beautiful, easy-to-use websites.
How to write HTML
HTML is the abbreviation of Hypertext Markup Language, which describes the structure and content of a web page. HTML uses markup to describe elements such as text, images, links, etc. The following are some basic tags of HTML:
<!DOCTYPE html> <html> <head> <title>我的网站</title> </head> <body> <header> <!-- 头部内容 --> </header> <nav> <!-- 导航栏内容 --> </nav> <main> <!-- 主体内容 --> </main> <footer> <!-- 底部内容 --> </footer> </body> </html>
<!DOCTYPE html> in the code is a document type declaration, which tells the browser that this is an HTML5 document. The <html> tag defines the root element of the document, while the <head> and <body> tags are used to define the head and body of the document. part.
In the <head> tag, we can add some elements, such as the <title> tag is used to display the title of the web page. <body>The tag can include the content of the page, such as text, images, tables, etc. Based on this, we can add other markup to complete the page.
How to write CSS
CSS is the abbreviation of Cascading Style Sheets, which defines the hierarchical structure and style of a web page. CSS applies styles to HTML elements. Here is some basic CSS syntax:
body {
background-color: #333;
color: #fff;
}
In this example, we are applying the style to the <body> element. The background-color attribute sets the background color of the element, and the color attribute sets the text color of the element. CSS styles can include more properties such as font, width, height, etc.
CSS can be applied to HTML elements in a variety of ways. Here are a few common methods:
- Internal style sheet: defined in the
<head>section of the HTML document. - External style sheet: Use the
<link>tag to link a .CSS file into the HTML document. - Inline styles: Define styles directly in HTML elements.
Here is an example of an external style sheet:
/* styles.css */
body {
background-color: #333;
color: #fff;
}
h1 {
font-family: Arial, sans-serif;
font-size: 32px;
text-align: center;
}
Link the .css file to HTML using the <link> tag In the document:
<!DOCTYPE html> <html> <head> <title>我的网站</title> <link rel="stylesheet" href="styles.css"> </head> <body> <header> <h1>欢迎来到我的网站！</h1> </header> <main> <p>这里是主体内容。</p> </main> <footer> <p>版权所有 © 2021</p> </footer> </body> </html>
In this example, the <link> tag points to the styles.css file, which contains the <body> Styles for and <h1> elements.
