Override user agent style for li element

I have the following html.

   <div class="alert alert-error" role="alert">        
        <ul>
            <li>This is test message.</li>
        </ul>
    </div>

I am using bootstrap alert. Alert styles are override in custom css to add ban-circle before the alert message.

.alert {
    padding: 5px;
    margin-bottom: 5px;
    color: white;
}   

.alert-error {
    background-color: rgb(186, 39, 39);
}

    /*Using a Bootstrap glyphicon as ban-circle*/
    .alert-error li:before {
        content: "\e090"; 
        font-family: 'Glyphicons Halflings';
        padding-right: 5px;
    }

UI shows the ban circle before alert message, but it also shows dot before the ban-circle. The dot is coming from user agent style sheet. I have <!DOCTYPE html> as suggested in this SO

How do I get rid of the dot from the User Agent Style?

Solution

You can get rid of the dot by using list-style-type property of CSS value none. You can read further about the property here.

I have used it in the following code:

.alert {
    padding: 5px;
    margin-bottom: 5px;
    color: white;
}

.alert-error {
    background-color: rgb(186, 39, 39);
}

/*Using a Bootstrap glyphicon as ban-circle*/

.alert-error li:before {
    content: "\e090";
    font-family: 'Glyphicons Halflings';
    padding-right: 5px;
}

ul {
    list-style-type: none;
}

<!DOCTYPE html>
<html lang="en">

        </ul>
