  • What are accessibility considerations in HTML, and why are they important?
    What are accessibility considerations in HTML, and why are they important?
    The core of making barrier-free design in HTML is to make the website available to everyone, including people with disabilities. There are four specific methods: 1. Use semantic tags such as reasonable title structure and form label binding to improve readability; 2. Add descriptive alt text to the picture and distinguish decorative pictures, and use text that clearly describes the target in the link; 3. Support keyboard navigation to ensure that interactive elements such as drop-down menus and modal boxes can be accessed logically through the Tab key; 4. ARIA attributes are used as supplements rather than substitutes, and native semantic tags are preferred, and only use ARIA to enhance interaction prompts when necessary.

  • How do I use the name attribute to give an input field a name that will be used when submitting the form?
    How do I use the name attribute to give an input field a name that will be used when submitting the form?
    Use the name attribute to define the field name when the form is submitted, and the server identifies the data type by this name. For example, name="email" will send user input as an email address. Correct usage methods include: 1. Use meaningful names such as username; 2. Avoid using spaces and special characters with first_name; 3. Keep the names of multiple forms consistent; 4. Share the names of related check boxes and add square brackets such as interests[]. Different input types handle differently. Radio buttons need to share names to ensure mutually exclusive selection. Different names should be used if the check box is independent. Common errors include missing name attributes, unrelated fields duplicate names, mismatch of front and back end names, etc., which may cause data to be located.

  • What are custom data attributes, and how do I use them to store custom data on HTML elements?
    What are custom data attributes, and how do I use them to store custom data on HTML elements?
    Custom data properties store additional information through attributes starting with data-, such as. Use JavaScript to access it through getAttribute or dataset, which will automatically convert kebab-case to camelCase. Application scenarios include storing user ID, product information and configuration values. Update data attributes can be used with dataset assignment or removeAttribute methods. Best practices include avoiding storing sensitive or complex data, not repeatedly saving existing information, not overly relying on its management state logic, and prioritizing class names over data attributes as the basis for CSS selectors.

  • How do I design and develop websites that are accessible to all users?

Clear structure: Use semantic HTML tags such as, etc. to divide the page structure, reasonably nest the title levels, and form elements bind the tags; 2. Visual and interactive design should consider diversity: ensure that the color contrast meets the standards, icons are matched with text descriptions, support keyboard navigation and avoid automatic playback of content; 3. There should be alternatives for pictures, videos and forms: add alt descriptions to the pictures, provide subtitles or text drafts, and form error prompts to clarify specific problems; 4. Testing and continuous optimization are the keys: use screen readers to test in person, scan problems with automation tools, listen to feedback from disabled users, and check accessibility synchronously when content is updated

  • What is the correct way to use heading HTML tags (h1-h6) for structure?
    What is the correct way to use heading HTML tags (h1-h6) for structure?
    The correct way to use title tags (H1–H6) is 1. Only one H1 tag per page represents the main title, such as the blog title "How to train your dog" should be used as H1; 2. H2 to H6 should be logically nested below H1, H2 is the main content part, H3 is the sub-part under H2, and so on, for example, "Basic Directive" is H2, "Sit down" and "Stay" are H3; 3. The title level should not be skipped for styles. If you go directly from H1 to H3, visual effects should be achieved through CSS rather than destroying the structure; 4. The title should be concise and descriptive, avoiding vague expressions, such as using "Set Training Space" instead of "Section 1". Doing so helps improve accessibility and SEO.
