A link to an element within a page called an anchor. In Joomla, anchor links can be created using text editors and in menu items.
The HTML source code for an anchor link might look like this:
<a href="#anchor">anchor link</a> <p id="anchor">Anchor.</p>
You can also link to an anchor placed on another page. To do this, you need to add the symbol # + the value of the id attribute of the element (anchor) to which the link leads to the URL of the page in the link:
<a href="/kategory/article#anchor">anchor link</a>
