The CSS display none property is commonly used with JavaScript to hide and show elements without deleting and recreating them. If this parameter is an observable value, the binding will update the element’s visibility whenever the value changes. visibility:hidden and display:none are totally different used in css property.

When the parameter resolves to a true-like value (e.g., the boolean value true, or a non- null object or array), the visible binding removes the value, causing it to become visible. This takes priority over any display style you’ve defined using CSS.

Let’s look at how you might attempt to solve this problem, step by step. display:none removes the element from the document. You want to use CSS for the animation, not a library.įor this reason, animating opacity to zero is simply not enough because an element with zero opacity still occupies the same space on the page. visibility:hidden hides the element, but it still takes up space in the layout.You don’t want that element to take up space after it has disappeared (i.e., you want the disappearance to cause reflow).You want to make an element gradually disappear visually from the page.The need to animate the display property comes from wanting to solve the following problem: But there are ways to work around it, and I’ll present one way here. how would you animate to “display: table”?).
