Angular-loading-bar + National flag on Dashboard

I added a national flag on the Main page
and include the angular-loading-bar dependency on my source code
after installing it using bower 
Not sure I understand what you mean.

As an example, in a bootstrap navbar there is the `.navbar-brand` class, which is as styled as follows on taarifa.org:

boostrap style:
```
.navbar-brand {
float: left;
padding: 15px;
font-size: 18px;
line-height: 20px;
height: 50px;
}
```
custom style:
```
.navbar-brand {
background: url(../taarifa_small.png) no-repeat left center;
margin-left: 0px;
padding-left: 45px;
}
```
