] | You need to [clear/contain the floated elements](http://www.quirksmode.org/css/clearing.html) in `.contentMainDiv`.
One way to do that is to add `overflow: hidden`. | You can add `float: left;` or `display: inline-block;` to `.contentHolder`
```
.contentHolder {
padding: 10px 0 0 10px;
border-left: 1px solid #CCC;
float: left;
}
```
Either should work. |

.contentHolder div.leftDiv{ float:left; width: 150px; }
```
remove float: left or use clearfix <http://perishablepress.com/press/2009/12/06/new-clearfix-hack/> for contentHolder class

.clearfix:after {

] | If I understand your question right - you looking for "how to set config param", then you can use `Config::set($key, $value)` | Correct answer is above
```
Config::set($key, $value)
```
Example
```
//Not forget to add namespace using class.
use Config;
//Example to set config. (configFile.key)
Config::set('auth.enable_verification', false);
