HTML’s handling of whitespace can be quite surprising, especially for those new to the language. Unlike many other programming languages, HTML doesn’t care about the number of spaces, tabs, or newlines you use between elements. It treats them as one single space, no matter how many spaces or line breaks you add in the code. This feature can make HTML a little "weird" at first, but it also offers flexibility and simplicity in organizing the code.

Whitespace behavior in HTML allows for greater readability and organization of code. Developers often add extra spaces or line breaks to make their HTML more readable without worrying about how it will affect the final presentation on the page. It makes it easier to format the code in a way that is clean and logical for developers to follow.

Moreover, you can add multiple spaces, line breaks, and tabs between HTML tags to make the code look more structured, without affecting the final layout of the webpage.
