Reply To: Breadcrumb css in dark colour style

On line 183 change the margins like this (or you can adjust however you need it to look) –

.breadcrumb {
font-size: 14px;
margin: 0 0 30px;
padding: 5px 10px;
}

Also, to change the background, look on line 100 for this –

blockquote, input, select, textarea, .author-box, .breadcrumb, .sticky, .taxonomy-description, .wp-caption {
background-color: #f2f2f2;
border: 1px solid #ddd;
}
