CSS - should it be written as all lowercase?

[Skinnybobb]

Hi,
I'm currently in an argument with a developer.

I say that all css should be written lower case - in the css file and when referenced in the html.

He says that it can have upper cases in it so it reads more easily.

E.g.

<class="tablemargin">

or

<class="TableMargin">

Who is right? If anyone?

<class="tablemargin">

or

<class="TableMargin">

CSS is case-sensitive, therefore both of your examples are correct; They are just two different references.

<style type="text/css">
element.tablemargin {/* lowercase styles */}

element.TableMargin {/* Firstcase styles */}
</style>

<element class="tablemargin"> ... </element>

<element class="TableMargin"> ... </element>

Not only CSS class should be case sensitive!

Though i have not tried as you have said, but according to me class name can be differentiated with upper and lower case.

I think this should help you

Good Day
