Backgroundimage
These classes help you to attach an image to background of an element. Image can be set using inline css and background-image property.
                            You should apply .bg-imgto your desire element. Then, you can modify the image behavior using following utility classes, or draw an overlay above it.
                        
| Class name | Description | 
|---|---|
| .bg-fixed | background-attachment: fixed | 
| .bg-repeat | background-repeat: repeat | 
| .bg-img-left | background-position: left center | 
| .bg-img-right | background-position: right center | 
<div class="bg-img h-300px" style="background-image: url(path/to/img.jpg)"></div>Overlays
Add a alpha colored layer between your background-image and element text for better contrast.
                            Elements using a background image can be overlayed with a dark layer by adding the data attribute data-overlay="*", where *is a number between 1 and 9; 1 is lighter layer and 9 is darker layer.
