CSS Form Properties

• HTML entities were described in the previous chapter.
  Many mathematical, technical, and currency symbols, are not present on a normal keyboard.
  To add such symbols to an HTML page, you can use an HTML entity name.
  If no entity name exists, you can use an entity number, a decimal, or hexadecimal reference.

                                                          What I have learned

Char	Number	Entity	Description
∀	∀	∀	FOR ALL
∂	∂	∂	PARTIAL DIFFERENTIAL
∃	∃	∃	THERE EXISTS
∅	∅	∅	EMPTY SETS
∇	∇	∇	NABLA
∈	∈	∈	ELEMENT OF
∉	∉	∉	NOT AN ELEMENT OF
∋	∋	∋	CONTAINS AS MEMBER
∏	∏	∏	N-ARY PRODUCT
∑	∑	∑	N-ARY SUMMATION

                What problem do I foresee happening?

It is really hard to remember all the symbols

How can I solve than now?

To save a copy in the computer and open it when I need it

What is happening that you did not expect?
It is not really commonly been used

What is the best thing that happened,why?
i think maybe is the many mathematical, technical, and currency symbols, are not present on a normal keyboard.
