always lower-case?

[Makaveli2007]

Should I always use lower-case letters when typing html (4.01 strict) or CSS code?

I thought I should do it, but it seems that for CSS sometimes people (including those who create html tutorials) use "Times New Roman" etc. instead of "times new roman".

1. HTML is case-insensitive.

2. XHTML is case-sensitive, lower-case only.

3. CSS is case-insensitive... but font-family declarations, URLs (eg. links to background images) may be case-sensitive. (In both situations, the case-sensitivity is not directly related to the CSS.)

What's more,

id

and

class

names are also case-sensitive, so

.myClass

is not the same as

.myclass

- so it is important to always remain consistent, and many people prefer using lower-case only to avoid problems.
