Problem :

How do you add more than one css class to an <img> using image_tag?

Using image_tag("image.png", :class => "class1, class2") seems not to work

Solution :

Don't separate the classes using a comma, separate them using a space...

image_tag("image.png", :class => "class1 class2")

Note: You cannot use a space inside a class name...separate them using _ or -, if you use space than class 1 class 2 will be like 4 classes in which all are invalid.
