Minimum Width Issue:

In Firefox and older versions of WebKit,

elements inherit a minimum width of "min-content," preventing them from shrinking below the width of their content. This issue can lead to problems when you expect

elements to resize based on their parent container's width.

Solution (for WebKit and Firefox 53 ):

Solution (for Firefox Pre-53):

To make the

display correctly in earlier versions of Firefox, change its display property to table-cell. To hide this fix from other browsers, use @-moz-document:

@-moz-document url-prefix() {
  fieldset {
    display: table-cell;
  }
}

Copy after login

Explanation:

This issue arises from inconsistencies in how browsers handle

s and how elements behave with different display properties. Firefox's rendering engine enforces a minimum width on

s unless they are rendered as table elements.
