By using display: none, the div will be hidden and so the whole menu as well. As you click on the hide menu link, the jQuery code will be used on the click event of that link to add: display: none property to the parent div.Īs such, the parent div contains the menu, which is the combination of ul, li and elements. Two links are given after the menu: hide menu / show menu. The links act as the menu items.Īpart from other CSS properties, that are many to design this menu, the display property is not used initially, that means the menu will be visible. In this demo, I have used a div element that contains unordered list, list items and hyperlinks. It will behave like a block element if the block value is used in display property.Ī display example to show / hide menu – div, li, and links For example, the span is an inline element. Using the block value makes the opposite. This is how you can use the CSS visibility property: See online demo and code Syntax of CSS visibility You can see the difference the DIV 3 is moved up and DIV 2 is not occupying any space. The third part, above section 3 is also showing only DIV 1 and DIV 3 while the DIV 2 is hidden by using the display: none property. The DIV 2 is given the visibility: hidden value, however, you can see the space of DIV 2 is still occupied. The second part, above section 2 in the figure is showing only DIV 1 and DIV 3. Initially, all div elements are shown without using the display or visibility properties. Three div elements are used that are shown in section 1 (from the left side). To understand that, see the figure below where I have used three div elements. If both are used to hide or show elements then what is the difference between the two? The display and visibility properties are used to show or hide HTML elements in web pages. In order to do that without breaking the layout, Chrome adds a CSS class named _web-inspector-hide-shortcut_ to the element. With Chrome DevTools, you can hide any element in the page by right clicking the element, and then click Hide element. Similarly, an element with visibility: hidden will have empty inner text (equivalent with the innerText property). Hence, all properties related to the element size, such as clientHeight, clientWidth, height, offsetHeight, offsetWidth, scrollHeight, scrollWidth and width are zero.Īll properties returned by the getBoundingClientRect() method are zero as well. It's worth noting that if you want to measure the size of element, then you can't use display: none at all.Īs mentioned in the first difference, an element with display: none doesn't take any space on the page. visibility: hidden, on the other hand, doesn't change the visibility of any children. Regarding the accessibility, opacity: 0 is the only property which makes the element accessible in the tab order, and the element's content can be read by screen readers.Īpplying display: none or opacity: 0 will effect on child elements. The visibility: hidden style behaves like a combination of opacity: 0 and pointer-events: none. The browser will not response to any events of element which uses either display: none or visibility: hidden. The other ways still take the space normally. There are three common CSS properties to make an element invisible:ĭisplay: none doesn't take space when the element is rendered.
