Bootstrap 5 Dark Mode

The following example assumes you're including necessary Bootstrap 5.3 JS and CSS as well as the data-bs-theme="dark" attribute to a parent element (such as html or an outer div tag). You can place the additional CSS and JS inside the formatting template or add to your site's CSS / JS files.

Please note that Dark Mode relies on features newly available in the Bootstrap 5.3.0-alpha1 version in order to work.

Formatting

Please note that you will need to include the data-bs-theme="dark" attribute to a parent element, such as <html> or an outer <div> tag.

CSS

The following CSS is a supplemental starting point to get forms appearing robustly.

.freeform-page-tabs {
margin: 30px 0;
}
.freeform-alert p:last-of-type {
margin-bottom: 0;
}
button[type='submit'].ff-loading {
display: inline-flex;
flex-wrap: nowrap;
align-items: center;
}
button[type='submit'].ff-loading:before {
content: '';
display: block;
flex: 1 0 11px;
width: 11px;
height: 11px;
margin-right: 10px;
border-style: solid;
border-width: 2px;
border-color: transparent transparent #fff #fff;
border-radius: 50%;
animation: ff-loading 0.5s linear infinite;
}
@keyframes ff-loading {
0% {
transform: rotate(0);
}
100% {
transform: rotate(1turn);
}
}
label.required:after {
content: '*';
color: #d00;
margin-left: 5px;
}
ul.errors {
display: block !important;
}
.is-invalid {
color: #dc3545;
}
.submit-align-left {
text-align: left;
}
.submit-align-right {
text-align: right;
}
.submit-align-center {
text-align: center;
}
.submit-align-center button:not(:first-of-type),
.submit-align-left button:not(:first-of-type),
.submit-align-right button:not(:first-of-type) {
margin-left: 5px;
}
.submit-align-spread button:first-child {
float: left;
}
.submit-align-spread button:last-child {
float: right;
}

/* DARK MODE SPECIFIC STYLES */
.opinion-scale.opinion-scale-scales>: first-child>label {
border-top-left-radius: 5px;
border-bottom-left-radius: 5px;
}
.opinion-scale .opinion-scale-scales > :last-child > label {
border-top-right-radius: 5px;
border-bottom-right-radius: 5px;
}
.opinion-scale .opinion-scale-scales li label {

JS

The following JS is a supplemental starting point to handle additional elements in the form.

// Styling for AJAX responses
document.addEventListener('freeform-ready', function (event) {
var freeform = event.target.freeform;
freeform.setOption('errorClassBanner', [
'alert',
'alert-danger',
'errors',
'freeform-alert',
]);
freeform.setOption('errorClassList', [
'help-block',
'errors',
'invalid-feedback',
]);
freeform.setOption('errorClassField', ['is-invalid', 'has-error']);
freeform.setOption('successClassBanner', [
'alert',
'alert-success',
'form-success',
'freeform-alert',
]);
});
// Styling for Stripe Payments field
document.addEventListener('freeform-stripe-styling', function (event) {
(event.detail.base = {
fontSize: '16px',
color: '#ffffff',
fontFamily:
'-apple-system,BlinkMacSystemFont,"Segoe UI",Roboto,"Helvetica Neue",Arial,sans-serif,"Apple Color Emoji","Segoe UI Emoji","Segoe UI Symbol","Noto Color Emoji"',
}),
(event.detail.invalid = {
color: '#dc3545',
});
});
