True or False: If a selector's display property is set to none, selected elements will still take up space on the page.

When a selector's display property is set to none, the selected elements do not take up any space on the page. This is because setting the display property to none effectively removes the element from the document flow. Consequently, the browser will not render the element, and surrounding elements will be able to occupy the space that would have been taken up by the element that is set to display none.

This behavior is central to CSS layout and design principles, allowing developers to manipulate the visibility of elements without leaving empty spaces in the layout. It's important to note that while the elements are still part of the DOM and can be manipulated through JavaScript or CSS, they are not visually represented in the user interface. Thus, the correct answer is that these elements will not occupy space in the layout when the display property is set to none.
