Difference Between display: none and visibility: hidden in CSS
display: none and visibility: hidden both make elements invisible, but they behave differently in how they affect the page layout and user interaction.
display: none removes the element from the layout flow — it occupies no space on the page.
visibility: hidden hides the element but still keeps its allocated space in the layout.
With display: none, the element and its children are not rendered at all.
With visibility: hidden, the element remains part of the document flow but is simply invisible.
Elements with display: none are not accessible by screen readers or focusable with the keyboard, while those with visibility: hidden may still be detected by assistive technologies.
In this example, the pink paragraph is completely removed from the layout, while the yellow paragraph remains invisible but still occupies space, leaving a visible gap.
Use display: none when you want to completely remove an element from the layout, such as when toggling visibility with JavaScript.
Use visibility: hidden when you want to hide an element but maintain its space, which can be useful for smooth animations or transitions.
Be mindful of accessibility — screen readers may still detect visibility: hidden elements but not display: none ones.
