Links & URLs

After this lesson, you can create absolute, relative, and fragment links with clear destination text.

BEGIN WITH A QUESTION

Understanding begins with a question.

If a page has three links named ‘click here’, could you identify each destination without reading the surrounding sentences?

Create absolute, relative, and fragment links with clear destination text.

UNDERSTAND THE CONCEPT

01

A connects; href defines the destination

An a element becomes a link when it has href. Its content is the text readers select. Describe the destination, such as ‘Read the HTML guide’, so the link makes sense on its own.

02

Full and relative addresses

An absolute URL such as https://developer.mozilla.org/ includes a scheme and domain. A relative path such as about.html looks for a file from the current document’s location. An href beginning with / starts at the site root, rather than the current folder.

03

Jump within the same page

Href="#jadwal" points to the element with id="jadwal". An id must be unique and spelled consistently. Use the same tab in this course; opening a new tab is optional. The exercise preview restricts outgoing navigation: check destinations through feedback and use file tabs to view other pages.

EXAMPLE / CONTEXT

Examples clarify concepts.

HTML EXAMPLE

<a href="https://developer.mozilla.org/">Read the MDN documentation</a>
<a href="about.html">About the community</a>
<a href="#jadwal">View the schedule</a>
<h2 id="jadwal">Study Schedule</h2>

BROWSER RESULT

One external link, one neighboring file, and one section on the same page. Each link names its destination.

TRY TOGETHER

Practice clarifies understanding.

<a ="about.html">About us</a>
Show a hint

This attribute differs from src on an image.

Try as often as you need. The independent task that follows records lesson completion.

WRITE · OBSERVE · UNDERSTAND

Three doors to knowledge

Create a descriptive link to https://developer.mozilla.org/, a link to about.html labeled ‘About the club’, and a fragment link to an h2 with id="koleksi". Give the h2 a collection title.

Suggestions use the language, snippets, and local code context. Formatting runs in your browser.

Document preview

Ctrl/⌘ + Enter runs the preview. Preview uses reading styles. Scripts and form submission are disabled. Sample illustration: assets/observatory.svg.

Return to the starter code?

All files in this task will be replaced with starter code. Completed lessons remain recorded.

TAKE THIS UNDERSTANDING WITH YOU

Practice gives a foundation.

  • Href defines the destination; link text explains it.
  • Relative paths depend on the document’s location.
  • A #name fragment points to id="name" on the page.
