JS: Finally discover how to Hide and Show elements

devlorenzo profile image DevLorenzo ・Updated on ・2 min read

Hello World! New episode of the series - A CSS/JS trick in 5 minutes - Last Article was about a CSS background that can really change your websites.
Today I want to explain you a Javascript trick: How to hide and show elements.

Check this!


We have a special property to change visibility of an element. Set visibility. We just have to call object.style.visibility. The property is supported in all browsers.

Show

object.style.visibility = "visible"
Enter fullscreen mode Exit fullscreen mode

Visible is the default property.

Hide

object.style.visibility = "hidden"
Enter fullscreen mode Exit fullscreen mode

Other values

object.style.visibility = "visible|hidden|collapse|initial|inherit"
Enter fullscreen mode Exit fullscreen mode

Parentheses about Display property:

You might get confused about visibility:hidden and display:none.

The visibility property allows the author to show or hide an element. It is similar to the display property. However, the difference is that if you set display:none, it hides the entire element, while visibility:hidden means that the contents of the element will be invisible, but the element stays in its original position and size. W3school

Display specifies how an element should be displayed, visibility makes an element hidden. Visibility will not affect the layout (so I recommend you to use it most of the time)

We have a lot of different display values, full list on w3school.

Also, I have to add, with "display: none" the element is still present in the DOM, with that if you set a button or a href link to "display: none" is still clickable even if it is not visible.
Thanks to @aspiiire πŸ”₯ for telling me.

Cool article, I would add that with "display: none" the element is still present in the DOM, with that I mean that if you set a button or a href link to "display: none" is still clickable even if it is not visible. πŸ™‚
