Adding custom class based on Bootstrap CSS 2.3.2

Question

I've included Bootstrap CSS, and now want to add a custom class in my own CSS file.

It is simply an exact copy of .btn-success with modified colors and class name only:

.btn-mine {
    color: #ffffff;
    background-color: #ff8d53;
    border-color: #ef8343;
}
.btn-mine:hover,
.btn-mine:focus,
.btn-mine:active,
.btn-mine.active,
.open .dropdown-toggle.btn-mine {
    color: #ffffff;
    background-color: #ea793e;
    border-color: #dc5930;
}
.btn-mine:active,
.btn-mine.active,
.open .dropdown-toggle.btn-mine {
    background-image: none;
}
.btn-mine.disabled,
.btn-mine[disabled],
fieldset[disabled] .btn-mine,
.btn-mine.disabled:hover,
.btn-mine[disabled]:hover,
fieldset[disabled] .btn-mine:hover,
.btn-mine.disabled:focus,
.btn-mine[disabled]:focus,
fieldset[disabled] .btn-mine:focus,
.btn-mine.disabled:active,
.btn-mine[disabled]:active,
fieldset[disabled] .btn-mine:active,
.btn-mine.disabled.active,
.btn-mine[disabled].active,
fieldset[disabled] .btn-mine.active {
    background-color: #ff8d53;
    border-color: #ff6314;
}
.btn-mine .caret {
    border-top-color: #fff;
}
.dropup .btn-mine .caret {
    border-bottom-color: #fff;
}

Unfortunately, this does not work, as shown here: http://jsfiddle.net/qG2n6/.

I know there are many 3rd-party Bootstrap button makers which can create buttons of any colors.

But I am more interested in knowing why my approach above does not work.

I copy all the styles that contains .btn-success in the original Bootstrap CSS, and only modify the colors and the class name, and I expected it to work.

What am I missing here?

Answer 1

.btn-success contains

.btn-success {
background-color: #5BB75B;
background-image: linear-gradient(to bottom, #62C462, #51A351);
background-repeat: repeat-x;
border-color: rgba(0, 0, 0, 0.1) rgba(0, 0, 0, 0.1) rgba(0, 0, 0, 0.25);
color: #FFFFFF;
text-shadow: 0 -1px 0 rgba(0, 0, 0, 0.25);

While your class contains just some border and background color
