HTML: References

In order to move between pages, one of the internet's main elements was invented, hyperlinks.

Hyperlinks allow you not only to go to a given resource on the Internet, but also allow you to move within a document or page you're looking at. You got to this lesson through a hyperlink, too.

To create a link, you use a paired <a> tag with the obligatory href attribute, which indicates the address of the page to which the link will go after it's clicked

<a href="link to a document">Link text</a>

Links can be divided into 3 types:

  • Relative. If you click on this type of link on a given website, it'll lead to the same site
  • Absolute. These allow you to navigate to third-party resources on the Internet
  • Anchors. These are used to move within a page or document you're currently looking at

The only difference between relative and absolute links is the format in which the link is specified. Relative links don't specify the address of the site that you will move to, it will be the same as the site you are currently on:

<!-- This link points to a document within the current site -->

<a href="/languages/html">Return to a lesson selection</a>
<!-- This link points to a document within the current site.
     In this case to the main page of Code Basics  -->

<a href="">Go to Code Basics</a>

Anchor links are easy to use within a large document and allow you to move the user to the right place. For example, if the page is a report, it's more convenient if you can quickly move back and forth between sections.

Creating an anchor link consists of two actions:

  1. The part of the page you want to move to, you need to specify a unique identifier. This is done using the id attribute
  2. Add an <a> tag, and in the href attribute specify a link in the form of #name-unique-identifier
<a href="#anchor">Go to 2nd chapter</a>
<div id="anchor">
    <h2>Chapter 2</h2>


Add an absolute link to the website

The exercise doesn't pass checking. What to do? 😶

If you've reached a deadlock it's time to ask your question in the «Discussions». How ask a question correctly:

  • Be sure to attach the test output, without it it's almost impossible to figure out what went wrong, even if you show your code. It's complicated for developers to execute code in their heads, but having a mistake before their eyes most probably will be helpful.
In my environment the code works, but not here 🤨

Tests are designed so that they test the solution in different ways and against different data. Often the solution works with one kind of input data but doesn't work with others. Check the «Tests» tab to figure this out, you can find hints at the error output.

My code is different from the teacher's one 🤔

It's fine. 🙆 One task in programming can be solved in many different ways. If your code passed all tests, it complies with the task conditions.

In some rare cases, the solution may be adjusted to the tests, but this can be seen immediately.

I've read the lessons but nothing is clear 🙄

It's hard to make educational materials that will suit everyone. We do our best but there is always something to improve. If you see a material that is not clear to you, describe the problem in “Discussions”. It will be great if you'll write unclear points in the question form. Usually, we need a few days for corrections.

By the way, you can participate in courses improvement. There is a link below to the lessons course code which you can edit right in your browser.

If you got stuck and don't know what to do, you can ask a question in our community
