The <address></address> element in HTML is used to mark up contact information for a person, organization, or author associated with a webpage or article. It’s not just about postal addresses — it can include phone numbers, email addresses, URLs, and even social media links.

When Should You Use the <address></address> Element?

Use it when you want to provide contact details that are relevant to the page or a specific section of the content. It’s especially useful in footers, author bios, or contact pages.

• If you're writing a blog post and want to show the author's contact info, wrap it in <address></address>.
• On a company contact page, use it to semantically group address, phone, and email.
• Avoid using it for generic addresses unrelated to contact purposes (like an address in a story or example).

This helps screen readers and search engines understand what the information is for.

What Kind of Content Fits Inside <address></address>?

It should contain contact information only. Here’s what typically goes inside:

• Physical address (e.g., “123 Main St, Cityville”)
• Email address
• Phone number
• Website URL
• Social media handles or links

Example:

<address>
  Contact us at <a href="mailto:info@example.com">info@example.com</a>  
  or visit our <a href="/contact">contact page</a>.
</address>

You don’t have to include all of these — just what makes sense for your context.

How Does <address></address> Affect Accessibility and SEO?

Using <address></address> properly adds meaning to your HTML structure, which benefits both accessibility and SEO.

• Accessibility: Screen readers may announce the presence of an address section, helping users navigate to important contact info quickly.
• SEO: Search engines can better understand the purpose of the content, potentially improving how your site is indexed for local searches or author-related queries.

However, don't expect a big SEO boost from this alone — it's more about semantic clarity than ranking improvements.

Styling the <address></address> Element

By default, browsers usually apply italic styling to the <address></address> element. But you can override that easily with CSS if needed.

Some tips for styling:

• Reset font style if italics don’t fit your design.
• Add spacing or icons next to links for visual clarity.
• Consider responsive layout for mobile screens when displaying multiple contact methods.

It behaves like a regular block-level element, so styling is straightforward.

基本上就這些。
