Bootstrap 4 white buttons and input groups with button addons

Bootstrap 4.x doesn't give you white buttons by default, but sometimes white buttons look better, particularly for something like a search box using an input group with button addon placed on a navbar.

Bootstrap 4.x doesn't give you white buttons by default, but sometimes white buttons look better, particularly for something like a search box using an input group with button addon placed on a navbar.

The outline classes for buttons almost accomplish this but there are some differences in border colours so they don't look quite right.

You can accomplish the perfect style with a new css class which I've called `btn-white` in my example:

.btn-white {
	background-color: #fff;
	border-color: #ced4da;
	color: #212529;
}

And sometimes input groups with button addons look even better if the border between the text box and the button is removed. There's a few CSS overrides that can achieve this look simply:

.input-group > .input-group-append > .btn-white {
	border-left: solid 1px #fff;
}

.input-group > .input-group-prepend > .btn-white {
	border-right: solid 1px #fff;
}

Here's the final product, with borders (top) and without (bottom).

As a side note, if you are looking for a way to show a magnifying glass without a custom font or image, you can use HTML entity `⌕`. Don't forget to provide a fallback for accessibility.
