Question

In CSS3, is there any attribute that takes false or null value? I suppose and expect not, but wanted to make sure.

I am writing a javascript code (related to ajax interaction) that sets or removes an attribute to/from some DOM object. The function takes an attribute name and its value as the arguments, and I am thinking that, if the value turns out to be false or null, then removeAttribute() function should be called, and otherwise, the attribute should be assigned with that value. If there is a style attribute that possibly takes false or null value, then I cannot do that, so I wanted to make sure.

Answer 1

No, there is no attribute that takes false or null. However, I am pretty sure you can create your property without any visual impact.
