7: HTML Link Structure Best Practices
What is it?
HTML link structure refers to how you organize and
manage hyperlinks within your HTML code. These links can point to other pages,
resources, or external websites.
Why is it
important?
- Navigation
and User Experience:
Links are a primary way users navigate your site. Properly structured
links improve the site usability.
- SEO: Search engines use links
to crawl and index pages.
- Maintainability: Well-organized links make
it easier to update and manage your content.
Key
Concepts
1.
Anchor Tag (<a>): The basic
element used to create hyperlinks.
<a href="https://www.example.com">Visit Example</a>
2.
Absolute vs.
Relative Links:
- Absolute
Link: A link
that includes the full URL.
Example:
<a href="https://www.example.com/about">About Us</a>
- Relative
Link: A link
that points to a resource relative to the current page. Example:
<a href="about.html">About Us</a>
3.
Descriptive
Link Text: Use clear and meaningful
link text for both accessibility and SEO. Avoid "click here" or
"read more".
<a href="/contact">Contact Us</a>
<a href="/contact">Click here</a>
4.
Linking to
External Sites: Use the target="_blank" attribute to open external links in a new tab.
<a href="https://www.example.com" target="_blank">Visit Example</a>
Exercise:
- Create a basic webpage with
multiple internal and external links.
- Make sure to use relative
links for internal pages and absolute links for external sites.
- Ensure that each link has
descriptive text.
Section
8: HTML Accessibility Best Practices
What is it?
Accessibility in HTML refers to making your
website usable for people with disabilities. This involves creating code that
is easy to navigate for people using screen readers, keyboard navigation, and
other assistive technologies.
Why is it
important?
- Inclusivity: Making your website
accessible ensures everyone can use it.
- SEO: Accessible websites tend
to have better SEO, as search engines also value accessibility.
- Legal
Compliance:
Many countries have laws requiring web accessibility.
Key
Concepts
1.
Alt Text for
Images: Provide a text description of
images for screen readers.
<img src="logo.png" alt="Company Logo">
2.
Semantic HTML: Use proper HTML elements that convey meaning (e.g., <header>, <footer>, <nav>) instead of generic <div> and <span> tags.
3.
Keyboard
Navigation: Ensure your site is
navigable using a keyboard. Use the tabindex attribute to
manage tabbing order.
4.
Labels for
Forms: Use the <label> tag to provide accessible labels for form inputs.
<label for="email">Email Address</label>
<input type="email" id="email" name="email">
5.
ARIA
(Accessible Rich Internet Applications):
Use ARIA roles and properties to enhance accessibility for complex web elements
like sliders or dynamic content.
Exercise:
- Create a simple form with a
label, input field, and submit button.
- Add alt text to any images.
- Test keyboard navigation by
using the "Tab" key to navigate through form fields and links.
