When creating internal links in HTML, how should the URL begin?

When creating internal links in HTML, the URL should begin with a forward slash. This indicates that the link is pointing to a location within the same domain, starting from the root of the website. By using a forward slash, you effectively signal the browser to look for the specified resource relative to the root directory, which is essential for maintaining the structure and integrity of internal navigation.

Using a full URL would be appropriate for external links, as it specifies the complete address, including the domain name, but it is not necessary for internal linking. A question mark is typically used in URLs to denote the beginning of query parameters, which are not relevant when simply linking to a page within the expected structure of the website. An underscore is not used to define or create links in HTML; it has specific purposes in programming and naming conventions but is not a standard for initiating URLs. Therefore, starting an internal link with a forward slash is the correct approach for ensuring seamless navigation within your website.
