HTML: Unique page content
Each HTML page contains unique content that is found only on that page. This area is marked with a paired
<main> tag. This will help devices for people with disabilities and web crawlers understand where the main content on the page is located faster.
Let's take the header we created and add an area with unique content to it:
<header> <img src="/logo.png" alt="Logo"> <!-- Site Logo --> <div id="menu"> <!-- Menu --> <ul> <li><a href="/">Home</a></li> <li><a href="/about">About</a></li> <li><a href="/contacts">Contacts</a></li> </ul> </div> </header> <main> <!-- The main content of the page. This can be an article, a description of a service, data, contact information, or a form to order a service --> </main>
main element is unique to one page. This reflects its semantic purpose, marking up unique content. When wrapping content in
main, it's important not to include non-unique areas:
- Site-wide navigation
- Site-wide header and footer
Place text/graphic content in
main. It's easy to find such content in online templates - it's not duplicated on other pages.
main element can have its own navigation areas, headers, sections, and other elements that will be studied in this module.
Create a website header. It should consist of 2 elements:
- Navigation section. It should contain a bulleted list with two elements
<main> section. Insert any content you want inside it.
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.
main is a unique section that is used once per page
In order to easily find an area that should be in
maintry to mentally remove the areas that are on every page. These are the ones that should not be located in the
