Question

I am new to the CSS. While reading CSS of a website it is writing as:

 .abc:before { content:"\9d005" }

I fully understood as:

• .abc - is the class

• :before - selector inserts something before the content of selected element

• content - used with :before or :after to insert generated content

What to understand what is:

Answer 1

It called ASCII code (Unicode).

The general format for a Unicode character inside a string is \000000 to \FFFFFF – a backslash followed by six hexadecimal digits.

Here is a list of examples , and this conversion tool might be useful.

In CSS, these Unicodes can be only used in :before , :after and ::marker CSS pseudo-element.
