Notice that at the bottom right corner of the VSCode window, there is a Go Live<\/strong> button.<\/p>\n\n
<\/p>\n\n
Clicking this button will activate the Live Server<\/strong> extension. A local development server will be started, hosting the index.html file you just created.<\/p>\n\n
<\/p>\n\n
Of course, the file is still empty right now, so you can't see anything. Add something between the

<p>HTML and CSS are the most fundamental building blocks of a webpage, and they are also your first step towards becoming a web developer. HTML provides the layout and content of the webpage, and CSS defines its style and appearance. In this tutorial, we are going to cover the basics of HTML and CSS, and by the end, you will be able to design responsive webpages that work seamlessly on devices of all sizes.</p>
<h2>
What is HTML?
</h2>
<p>HTML is the standard markup language used to create webpages. It defines the structure and content of webpages using HTML elements such as headings, paragraphs, images, links, forms, and more.</p>
<p>To start writing HTML code, you can use the CodePen demo below:</p>
<p>Code Demo ?</p>
<p>On the left side, you will find the HTML source code, which is essentially the blueprint for what will be displayed. The browser will then transform this blueprint into the webpage you see on the right side.</p>
<p>You can modify the source code directly to see how it affects the displayed webpage.</p>
<h2>
Prepare your computer for web development
</h2>
<p>Of course, in practice, you cannot rely on tools such as CodePen to create a working and fully featured web application. You need something more powerful, so, let's set up your computer for web development.</p>
<p>To get started, make sure you have a browser installed. Any popular web browser such as Google Chrome, Microsoft Edge, Safari, or Firefox, should be sufficient for this course. You may download and install the browser from the linked websites.</p>
<p>In addition, you'll need a code editor to write and edit your code. Visual Studio Code is a great option for beginners (and professionals, for that matter). It is the most commonly used code editor in the world. Simply download the appropriate installer for your operating system from their official website.</p>
<p><img src="/static/imghw/default1.png" data-src="https://img.php.cn/upload/article/000/000/000/173617271157796.jpg" class="lazy" alt="Fundamentals of HTML and CSS"></p>
<p>After you've installed VSCode, make sure to install the <strong>Live Server</strong> extension as well. Navigate to the <strong>Extensions</strong> tab on the left sidebar, and type in <strong>Live Server</strong> in the search box. From there, you'll be able to download and install the extension.</p>
<p><img src="/static/imghw/default1.png" data-src="https://img.php.cn/upload/article/000/000/000/173617271255420.jpg" class="lazy" alt="Fundamentals of HTML and CSS"></p>
<p><strong>Live Server</strong> will create a local development server with the auto-reload feature. For example, create a new work directory and open it using VSCode.</p>
<p><img src="/static/imghw/default1.png" data-src="https://img.php.cn/upload/article/000/000/000/173617271512988.jpg" class="lazy" alt="Fundamentals of HTML and CSS"></p>
<p>Create a new file named index.html under this directory. The .html extension indicates that this is an HTML document. Type in ! in VSCode, and you will see suggestions like this:</p>
<p><img src="/static/imghw/default1.png" data-src="https://img.php.cn/upload/article/000/000/000/173617271776671.jpg" class="lazy" alt="Fundamentals of HTML and CSS"></p>
<p>This is a shortcut for creating HTML documents quickly. You can navigate with the ↑ or ↓ keys. Select the first option, and the following code should be generated.<br>
</p>
<pre class="brush:php;toolbar:false"><!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Document</title>
</head>
<body></body>
</html>
</pre>
<p>Notice that at the bottom right corner of the VSCode window, there is a <strong>Go Live</strong> button.</p>
<p><img src="/static/imghw/default1.png" data-src="https://img.php.cn/upload/article/000/000/000/173617271945701.jpg" class="lazy" alt="Fundamentals of HTML and CSS"></p>
<p>Clicking this button will activate the <strong>Live Server</strong> extension. A local development server will be started, hosting the index.html file you just created.</p>
<p><img src="/static/imghw/default1.png" data-src="https://img.php.cn/upload/article/000/000/000/173617272021543.jpg" class="lazy" alt="Fundamentals of HTML and CSS"></p>
<p>Of course, the file is still empty right now, so you can't see anything. Add something between the <body> and
</body> tags.<br>
</p>
<pre class="brush:php;toolbar:false"><!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Document</title>
</head>
<body>
Hello, world!
</body>
</html>
</pre>
<p>Save the changes, and the webpage will be automatically refreshed with the new content.</p>
<p><img src="/static/imghw/default1.png" data-src="https://img.php.cn/upload/article/000/000/000/173617272129442.jpg" class="lazy" alt="Fundamentals of HTML and CSS"></p>
<h2>
The structure of an HTML document
</h2>
<p>A typical HTML document always has the following structure:<br>
</p>
<pre class="brush:php;toolbar:false"><!DOCTYPE html>
<html lang="en">
<head>
. . .
</head>
<body>
. . .
</body>
</html>
</pre>
<p>The <!DOCTYPE html> tag defines the document type. When the web browser encounters <!DOCTYPE html>, it understands that the page should be parsed and displayed according to the specifications of HTML5, the latest version of HTML standard. This ensures that modern browsers interpret the webpage's content and layout correctly.</p>
<p>Everything else in the file should be enclosed inside an <html> element, defined by an opening tag (<html>) and a closing tag (</html>).</p>
<p>lang is called an attribute, and it has the value "en". This tells the browser as well as the search engine that English is the primary language used for this webpage.</p>
<p>Inside the <html> element, there are two child elements, <head> and <body>. <head> contains metadata and other information about the HTML document. This information will not be displayed in the browser but is often used by search engines for SEO (Search Engine Optimization) purposes.</p>
<p><body>, on the other hand, contains the main content of the webpage that is visible to the users, and for that reason, it is also the part of the HTML file we are going to focus on in this course.</p>
<h2>
Elements and attributes
</h2>
<p>Let's take a closer look at the previous example and notice that the HTML document comprises different elements in a nested structure. In HTML, most elements have both an opening tag and a closing tag:<br>
</p>
<pre class="brush:php;toolbar:false"><!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Document</title>
</head>
<body></body>
</html>
</pre>
<p>In this case, <tag> is the opening tag, and </tag> is the closing tag, and together, they form an HTML element. An element could hold textual content between the opening and closing tags.<br>
</p>
<pre class="brush:php;toolbar:false"><!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Document</title>
</head>
<body>
Hello, world!
</body>
</html>
</pre>
<p>The element can also wrap around other elements, forming a nested structure.<br>
</p>
<pre class="brush:php;toolbar:false"><!DOCTYPE html>
<html lang="en">
<head>
. . .
</head>
<body>
. . .
</body>
</html>
</pre>
<p>Inside the opening tag, you can define attributes, which are used to specify additional information about the element, such as its class, id, and so on.<br>
</p>
<pre class="brush:php;toolbar:false"><tag>. . .</tag>
</pre>
<p>The attribute is usually in a key/value pair, and the value must always be enclosed inside matching quotes (double or single).</p>
<p>There are some exceptions to these general formats. For example, the <br> element, which creates a line break, does not need a closing tag. Some attributes, such as multiple, do not require a value. We will discuss these exceptions later in this course as we encounter them.</p>
<p>However, you should remember that if an element does require a closing tag, then it should never be left out. In most cases, the webpage could still render correctly, but as the structure of your HTML document grows more complex, unexpected errors may occur. Take a look at our best practice guidelines for writing HTML and CSS if you are interested.</p>

<p class="Articlelist_txts_p">There are three ways to create a CSS loading rotator: 1. Use the basic rotator of borders to achieve simple animation through HTML and CSS; 2. Use a custom rotator of multiple points to achieve the jump effect through different delay times; 3. Add a rotator in the button and switch classes through JavaScript to display the loading status. Each approach emphasizes the importance of design details such as color, size, accessibility and performance optimization to enhance the user experience.</p>

<p class="Articlelist_txts_p">To deal with CSS browser compatibility and prefix issues, you need to understand the differences in browser support and use vendor prefixes reasonably. 1. Understand common problems such as Flexbox and Grid support, position:sticky invalid, and animation performance is different; 2. Check CanIuse confirmation feature support status; 3. Correctly use -webkit-, -moz-, -ms-, -o- and other manufacturer prefixes; 4. It is recommended to use Autoprefixer to automatically add prefixes; 5. Install PostCSS and configure browserslist to specify the target browser; 6. Automatically handle compatibility during construction; 7. Modernizr detection features can be used for old projects; 8. No need to pursue consistency of all browsers,</p>

<p class="Articlelist_txts_p">Setting the style of links you have visited can improve the user experience, especially in content-intensive websites to help users navigate better. 1. Use CSS's: visited pseudo-class to define the style of the visited link, such as color changes; 2. Note that the browser only allows modification of some attributes due to privacy restrictions; 3. The color selection should be coordinated with the overall style to avoid abruptness; 4. The mobile terminal may not display this effect, and it is recommended to combine it with other visual prompts such as icon auxiliary logos.</p>

<p class="Articlelist_txts_p">Use the clip-path attribute of CSS to crop elements into custom shapes, such as triangles, circular notches, polygons, etc., without relying on pictures or SVGs. Its advantages include: 1. Supports a variety of basic shapes such as circle, ellipse, polygon, etc.; 2. Responsive adjustment and adaptable to mobile terminals; 3. Easy to animation, and can be combined with hover or JavaScript to achieve dynamic effects; 4. It does not affect the layout flow, and only crops the display area. Common usages are such as circular clip-path:circle (50pxatcenter) and triangle clip-path:polygon (50%0%, 100 0%, 0 0%). Notice</p>

<p class="Articlelist_txts_p">To create responsive images using CSS, it can be mainly achieved through the following methods: 1. Use max-width:100% and height:auto to allow the image to adapt to the container width while maintaining the proportion; 2. Use HTML's srcset and sizes attributes to intelligently load the image sources adapted to different screens; 3. Use object-fit and object-position to control image cropping and focus display. Together, these methods ensure that the images are presented clearly and beautifully on different devices.</p>
