How to use Greek letters in HTML pages

Greek letters are a very commonly used series of symbols, especially in scientific and technological fields such as mathematics and physics, where they are often used to represent constants or variables with specific meanings. There are two ways to use Greek in web pages. One is to use the form of "&str", that is, add a prefix "&" to the corresponding string, and then you can output the corresponding Greek letter in the web page. This string is the English string corresponding to the Greek letter:

Uppercase Greek letters	HTML Characters	Lowercase Greek letters	Lowercase Greek characters
Alpha	Α	α	α
Β	Β	β	β
Γ	Γ	γ	γ
Δ	Δ	δ	δ
Ε	Ε	ε	ε
７	Ζ	ζ	ζ
Η	Η	η	η
Θ	Θ	θ	θ
Ι	Ι	ι	ι
K	Κ	κ	κ
Λ	Λ	λ	λ
Μ	Μ	μ	μ
N	Ν	ν	ν
Ξ	Ξ	ξ	ξ
Ο	Ο	ο	ο
Π	Π	π	π
P	Ρ	ρ	ρ
Σ	Σ	σ	σ
Τ	Τ	τ	τ
Υ	Υ	υ	υ
Φ	Φ	φ	φ
Χ	Χ	χ	χ
Ψ	Ψ	ψ	ψ
Ω	Ω	ω	ω

Another way is to use Unicode characters to represent Greek characters. In the Unicode code table, Greek letters and Coptic letters are placed together:

Unicode

\u037

;

\u038

\u039

Alpha

７

\u03A

\u03B

\u03C

\u03D

\u03E

\u03F

You can directly use the 4-digit hexadecimal Unicode code of the Greek letter to represent it, and fill the fourth digit with the corresponding hexadecimal value in the column above. If the corresponding site is displayed as a rectangular box, it means that there is no corresponding supporting software on the computer, so it cannot be displayed correctly. It may also be that the corresponding site is originally empty.
