HTML Display
You cannot be sure how HTML will be displayed.
Large or small screens and resized windows will create different results.
With HTML, you cannot change the output by adding extra spaces or extra lines in your HTML code.
The browser will remove any extra spaces and extra lines when the page is displayed.
Don't Forget the End Tag
Most browsers will display HTML correctly even if you forget the end tag.
Note: Dropping the end tag can produce unexpected results or errors.
HTML Line Breaks
The HTML <br> element defines a line break.
Use <br> if you want a line break (a new line) without starting a new paragraph.
The HTML <pre> Element
The HTML <pre> element defines preformatted text.
The text inside a <pre> element is displayed in a fixed-width font (usually Courier), and it preserves both spaces and line breaks.
