I know this is off topic but every time an equal sign is used are quotation marks used?

Answer 1

May be issues will be faced in next versions if quotations mark aren't used It's always better to be on safe side. Otherwise you will have to do many changes in your website if you didn't changed habbit of not using it in future.

Answer 2

You are not off topic. Even if it works without the quotation marks, you should always use them.

Answer 3

when you create a button for example <button class="btn btn-default"> I've declared 2 separate classes inline....if I don't use quotation marks first one will only work.....always use quotations so it becomes habit and no extra thinking required.....
