How do i keep my input fields in the same place regardless of the error message being displayed or n-CodePudding

I am developing a form which has certain error message when there is an error in the form. My problem is when ever the error message is displayed my form inputs are displayed as i wanted. This is the image which shows the display i want (this is with the error display property being commented out. It was display:none)

But when the display property(display:none) is active the input fields tend to shift their position like this

What should i change in the code to make sure that my text input fields should look somehow like this.

How do i achieve this.

My code is below:

Thank you.

CodePudding user response：

Instead of display: none;, which removes elements from the document, you can use visibility: hidden. Setting the visibility hides the element without changing the layout of a document. Another option that would work similarly, would be opacity: 0.

Both of these options are fine for sighted users, but you should also set aria-hidden to true when they are not visible to avoid the errors being read by screen readers.
