The colours on the page
The rules are the ones Quran.com paints. The colours are Nur’s — each rule a different light, so the eye can tell a stretch from a bounce from a nasal.

Madd — the stretches
A long vowel is held. The count depends on what follows it.
- مَا
Madd tabii
مد طبيعي
2 counts
A long vowel (ا و ي) is not followed by hamza or sukun. This is the ordinary stretch every reciter uses.
مَالِكِ1:4 - جَا
Madd wajib muttasil
مد واجب متصل
4–5 counts
A long vowel is followed by a hamza in the same word (madd wajib muttasil).
جَآءَ89:23 - فِى
Madd jaiz munfasil
مد جائز منفصل
2, 4 or 6 counts
A long vowel is followed by a hamza in the next word (madd jaiz munfasil). You may shorten.
فِىٓ أَنفُسِكُمْ2:235 - الْ
Madd lazim
مد لازم
6 counts
A long vowel is followed by a shaddah or a sukun that never lifts (madd lazim). Never shorten.

Ikhfa
إخفاء
2 counts, hidden

Idgham — merging
Two letters become one, with or without the nasal.

مِن وَاقٍ13:34 - مِن

لَهُم مَّا2:16
Qalqalah — the bounce
Five letters bounce when they carry sukun.

a bounce
ق ط ب ج د with sukun — in the middle of a word, a light bounce; at a stop, a fuller bounce.

Written, not said
Hamzat al-wasl and the sun lam are on the page, not on the tongue.
- الش
Lam shamsiyyah
لام شمسية
not pronounced
The lam of ال before a sun letter (ت ث د ذ ر ز س ش ص ض ط ظ ن). The next letter takes a shaddah.
الشَّمْس91:1 - بِس
Hamzat al-wasl

silent when joining
Hamzat al-wasl is dropped when a word before it carries you through (بِسْمِ ٱللَّهِ).
