    What are the accessibility considerations when writing HTML?
    When writing HTML, you should pay attention to accessibility to ensure that all users can use the web page smoothly. 1. Use semantic tags such as, , etc. instead of meaningless sum to help screen readers understand the page structure; 2. Each input box in the form should be added and bound to the id through the for attribute to clearly identify the input content; 3. All alt attributes need to be provided to describe the image content or function, and the decorative pictures should be set alt=""; 4. Use ARIA carefully and only supplement the ARIA attributes when the native HTML tag cannot express the meaning to avoid confusion caused by abuse. These details can significantly improve the accessibility of the web page.

    Understanding the HTML `` element for form controls.
    Tags are crucial in HTML forms because they not only provide text descriptions, but also improve usability and accessibility.

  • Managing hyperlinks in HTML with the `` tag and its attributes.
    Managing hyperlinks in HTML with the `` tag and its attributes.
    Managing hyperlinks in HTML mainly relies on tags, and the key is to understand and flexibly use common attributes. 1.href is a necessary attribute, used to specify the jump address; 2.target controls the opening method, and often cooperates with rel="noopener" to improve security; 3.title provides auxiliary prompt information, but it is not suitable as a key description; 4.download is used to control file download behavior, and can specify the download file name, but it may be invalid for cross-domain links. Rationally using these attributes can make the link clearer and safer and meet diverse needs.

  • What are self-closing tags in HTML?
    What are self-closing tags in HTML?
    Self-closing tags are elements in HTML that do not require closed tags because they do not contain content. Common examples include: ① Insert pictures; ② Add line breaks; ③ Create horizontal lines; ④ Define form input; ⑤ Link external resources; ⑥ Provide metadata. These tags work through attributes such as or. There are two correct ways to write: standard HTML syntax, such as XHTML style, but HTML5 recommends the former. Note that you cannot use self-closed form on labels that require the package content. If the error is wrong, it should be changed to a correctly closed Hello. Proper use of self-closing tags helps keep your code simple and efficient, and improves compatibility with other tools such as frameworks.

  • How to use the style html attributes for inline CSS?
    How to use the style html attributes for inline CSS?
    It is actually very simple to write inline styles using HTML's style attribute. Just add style="..." to the tag and then write CSS rules in it. 1. The basic writing method is CSS style with the attribute value in the form of a string. Each style is separated by a semicolon. The format is the attribute name: attribute value. For example: this paragraph of text is red. Note that the entire style string should be wrapped in double quotes. Each CSS attribute should be added with a semicolon after it. The attribute name is standard writing method of CSS; 2. Applicable scenarios for inline styles include dynamic style control, email template development and rapid debugging, such as allowing the picture to be displayed in the center to be written; 3. Several pitfalls that need to be avoided include high priority but difficult to maintain, many code repetitions, and special characters.
