When you get Bootstrap 2.3.2, you can select what you do/do not include. I noticed when going through the 3.0.8 CSS that the alert-class code is not in Customizr. This is what was left out:
/*--------------------- ALERT NOT IN ORANGE
.alert {
padding: 8px 35px 8px 14px;
margin-bottom: 20px;
text-shadow: 0 1px 0 rgba(255, 255, 255, 0.5);
background-color: #fcf8e3;
border: 1px solid #fbeed5;
-webkit-border-radius: 4px;
-moz-border-radius: 4px;
border-radius: 4px;
}
.alert,
.alert h4 {
color: #c09853;
}
.alert h4 {
margin: 0;
}
.alert .close {
position: relative;
top: -2px;
right: -21px;
line-height: 20px;
}
.alert-success {
background-color: #dff0d8;
border-color: #d6e9c6;
color: #468847;
}
.alert-success h4 {
color: #468847;
}
.alert-danger,
.alert-error {
background-color: #f2dede;
border-color: #eed3d7;
color: #b94a48;
}
.alert-danger h4,
.alert-error h4 {
color: #b94a48;
}
.alert-info {
background-color: #d9edf7;
border-color: #bce8f1;
color: #3a87ad;
}
.alert-info h4 {
color: #3a87ad;
}
.alert-block {
padding-top: 14px;
padding-bottom: 14px;
}
.alert-block > p,
.alert-block > ul {
margin-bottom: 0;
}
.alert-block p + p {
margin-top: 5px;
}
--------------------- END ALERT NOT IN ORANGE */
N.B. This was for Customizr 3.0.8. Thinkgs may have changed in 3.0.9.
It could be that you simply paste this CSS into your own child CSS and it will work. But I suspect that if the Bootstrap tool was told to leave it out, then there may be some backend stuff missing too—in which case, it won’t.
Try it and let us know.
