Tags: javascript, html, css
Published: 2022-12-19 09:49:23


Dans l article,On va créer un compteur à rebours.
Le compteur est double en ce sens qu'il passe de la séance de travail à la séance de repos.
Le période initiale de travail est de 25 minutes et celle de repos est de 5 minutes.Que l on peut personnaliser selon le desire.
La partie gauche, contient le réglage de minuteur et la partie droite c est pour le réglage de la pause!! la pause est dans l intervalle de 5 à 15 minute et le minuteur d une minute à une heure ou 60 minutes!!

### 
Pour la realisation de ce pomodoro,On a utiliser 3 feuilles:
1. Une feuille Html,
2.    Une feuille de style et
3.    Une feuille JavaScript

**1.Feuille Html**
     Cette feuille contient les balyses Html
