  • 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 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.
