Where is the btn-default gone in bootstrap 4

Question

according to the bs3 to bs4 migration docs:

Buttons

Renamed .btn-default to .btn-secondary.

But the secondary does not look at all as the old default button.

I mean the white shaded button/dropdown etc...

When I do btn-light that is not the original btn-default.

So how do I get my default theme back for buttons/dropdowns etc... ?

AFAIR literally now... there was a correct default button in the bs4 but it was in a former alpha version. I guess thats true.

Answer 1

The btn-outline-secondary class in Bootstrap 4 generates the closest to what used to be btn-default in Bootstrap 3.

That seems to be "typo" there in the docs.

primary is the blue button/color and secondary is the grey ones.

And the very light grey is btn-light.

Here's the reference link for Bootstrap 4 buttons:

add this css to your stylesheet file problem gone

.btn-default {
    color: #333;
    background-color: #fff;

}
.btn-default:focus {
