Quick takeaways
- To visually hide elements in CSS, use 'display: none' to completely hide the element and 'visibility: hidden' to visually hide the item while maintaining its space in the document flow.
- To control element interactivity, utilize properties like 'pointer-events: none' to disable click events and 'user-select: none' to prevent text selection, allowing elements to remain displayed but without interactive functionality.

Hiding Elements in CSS
To visually hide elements in CSS, there are several options. The 'display: none' property completely hides the element from the page and screen readers. 'visibility: hidden' visually hides the item but maintains its space in the document flow. It is important to note that 'visibility: hidden' is not hidden from screen readers, which can be addressed by using 'aria-hidden=true'. Additionally, using 'opacity: 0' achieves a similar effect to 'visibility: hidden' and is often used for fading elements in.
