Improve web development skills: Master the skills of using HTML global attributes

In today's digital era, web development is a very important skill. As more and more people are involved in web development, mastering the skills of using HTML global attributes will make your web pages better in terms of user experience.

HTML (Hypertext Markup Language) is the basic language for building the structure of web pages. Global attributes are attributes that can be applied to any HTML element and provide some common functionality to the element. Next, let's take a look at some commonly used HTML global attributes and their usage techniques.

1. class attribute (class attribute) - The class attribute is used to define one or more class names for an element. Class names are very useful in CSS to help you select and style specific elements. Here is an example:

<div class="container">
  <h1>Hello, World!</h1>
</div>

In the above example, we defined a "container" class for the div element using the class attribute. In CSS, we can use ".container" to select this specific div element and add arbitrary styles to it.

2. id attribute (identification attribute) - The id attribute is similar to the class attribute, except that it can only be applied to one element and should be unique. In CSS, it is very convenient to use the id attribute to select a specific element for styling. The sample code is as follows:

<h1 id="title">Hello, World!</h1>

In the above code, we use the id attribute to define a "title" identification for the h1 element. In CSS, we can use "#title" to select this specific h1 element for styling.

3. style attribute (style attribute) - The style attribute is used to define inline styles for an element. Inline styles are styles that are applied directly to an element and have higher priority than external style sheets. Here is an example:

<p style="color: red; font-size: 20px;">This is a red paragraph with font size 20px.</p>

In the above example, we used the style attribute to define some inline styles for the p element, including color and font size. In this way, we can directly style specific elements without using CSS style sheets.

4. title attribute (title attribute) - The title attribute is used to provide additional information to an element that will be displayed as a tooltip when the mouse is hovered over the element. Here is an example:

<a href="https://www.example.com" title="Visit Example Website">Visit Example</a>

In the above example, we use the title attribute to provide a "Visit Example Website" tooltip for the link element. When the user hovers over the link, the tooltip will appear.

1. Use class and id attributes wisely: Make sure to choose a suitable class name and unique identification for the element so that it is accurate in CSS Apply styles.
2. Try to use external style sheets: Although inline styles are convenient, it is best to put styles in external style sheets, which is beneficial to code organization and maintenance.
3. Avoid abusing inline styles: Reduce the use of style attributes on elements as much as possible, and it is recommended to use external style sheets for styling.
4. Use the title attribute to provide necessary information: Provide the title attribute for elements that require additional explanation so that users can learn more about the element.
