HTML process

HTML (HyperText Markup Language, Hypertext Markup Language) is a standardized language for creating web pages and other online documents. It consists of elements, identified by tags, which tell the browser how to present the content of the web page to the user. In this article, we will explore the basic flow of HTML.

  1. Define the basic structure of a web page

An HTML document always begins with the 8b05045a5be5764f313ed5b9168a17e6 statement, which tells the browser this The document is an HTML5 document. Then, we use the 100db36a723c770d327fc0aef2ce13b1 tag to define the beginning and end of the entire web page, like this:

<!DOCTYPE html>
<html>
<head>
  <title>我的网页</title>
</head>
<body>
  <!-- 网页内容在这里 -->
</body>
</html>

Within the 100db36a723c770d327fc0aef2ce13b1 tag, we respectively Use the 93f0f5c25f18dab9d176bd4f6de5d30e and 6c04bd5ca3fcae76e30b72ad730ca86d tags to define the head and body of the web page. In the header, we can define the metadata of the web page, such as title, keywords, and web page description. In the main section, we place our web page content.

  1. Add text content and style

In the 6c04bd5ca3fcae76e30b72ad730ca86d tag, we can use various HTML elements to add text content, such as Titles, paragraphs, lists, links, etc. For example:

<h1>欢迎来到我的网页</h1>

<p>这是一段文本内容。Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nunc nisl justo, feugiat vel ante quis, placerat finibus eros.</p>

<ul>
  <li>列表项一</li>
  <li>列表项二</li>
  <li>列表项三</li>
</ul>

<a href="https://www.example.com/">这是一个链接</a>

In the above code, we use the 4a249f0d628e2318394fd9b75b4636b1 tag to display the title, e388a4556c0f65e1904146cc1a846bee tag to add a paragraph, # The ##ff6d136ddc5fdfeffaf53ff6ee95f185 and 25edfb22a4f469ecb59f1190150159c6 tags create an unordered list, and the 3499910bf9dac5ae3c52d5ede7383485 tag creates a hyperlink.

At the same time, we can use CSS (Cascading Style Sheets, cascading style sheets) to control the style of our web pages. We can include style code in the header using the

c9ccee2e6ea535a969eb3f532ad9fe89 tag. For example:

<style>
  body {
    background-color: lightblue;
  }

  h1 {
    color: white;
    text-align: center;
  }

  p {
    font-family: verdana;
    font-size: 20px;
  }

  a {
    color: blue;
    text-decoration: none;
  }
</style>

In this example, we define a light blue background for the entire web page, center the text in the title center, and define a font called "verdana" and a paragraph with a size of 20px . We also define the color of the link, making it blue and removing the underline.

    Insert images and other media
Use the

a1f02c36ba31691bcfe87b2722de723b tag to add images to our web pages. For example:

<img src="https://www.example.com/image.jpg" alt="一张图片">

In this example, we display an image called "image.jpg" and add a description of "an image" so that screen reading software can understand the content of the image.

We can also embed audio and video files in web pages. For example:

<audio controls>
  <source src="audio.mp3" type="audio/mpeg">
  <source src="audio.ogg" type="audio/ogg">
  Your browser does not support the audio tag.
</audio>

<video width="320" height="240" controls>
  <source src="video.mp4" type="video/mp4">
  <source src="video.ogg" type="video/ogg">
  Your browser does not support the video tag.
</video>

In this example, we added an audio and a video file. The

e02da388656c3265154666b7c71a8ddc tag allows us to specify multiple audio or video files, and the browser will choose a supported format to play them. controls Property enables the player UI.

    Use of forms
Using forms, users can submit data to our website. We can use various form elements in web pages, such as text boxes, radio boxes, check boxes, drop-down boxes, etc. For example:

<form>
  <label for="firstname">名字:</label>
  <input type="text" id="firstname" name="firstname"><br>

  <label for="lastname">姓氏:</label>
  <input type="text" id="lastname" name="lastname"><br>

  <label for="gender">性别:</label>
  <input type="radio" id="male" name="gender" value="male">
  <label for="male">男</label>
  <input type="radio" id="female" name="gender" value="female">
  <label for="female">女</label><br>

  <label for="country">国家:</label>
  <select id="country">
    <option value="china">中国</option>
    <option value="usa">美国</option>
    <option value="uk">英国</option>
  </select><br>

  <input type="submit" value="提交">
</form>

In this example, we create a basic form that contains elements such as first name, last name, gender, and country selection. We use the

2e1cf0710519d5598b1f0f14c36ba674 label to identify each form element, and set the element's type attribute in the d5fd7aea971a85678ba271703566ebfd label.

    Complete the optimization of web pages
Finally, when writing HTML code, we should always maintain the accessibility and usability of web pages. In this regard, we should add appropriate markup to web pages to make them easy to use assistive technologies such as screen readers. We should also follow good SEO (Search Engine Optimization) practices so that search engines can easily index our web pages.
