Change Views Style

Sometimes we need to change the visual way of a view in Drupal.
It's a very easy question if you know how the css styles works.
You have to access to edit mode of your view and modify the Basic Setting --> CSS Class param setting the custom class which will be place in our style.css file.
For example gridCustomStyle
In our . css file we will create a class
.gridCustomStyle {
# Define custom properties
}
