Dark Mode ToggleHTML, CSS & JavaScript Project

Dark Mode Toggle project preview

Project Description

In this project, we'll create a toggle button that switches the website between dark and light modes, with a sliding animation for a more visually appealing transition. We'll use keyframe CSS queries to create the animation and JavaScript to change the background color dynamically. The user's preference will be stored using the browser's local storage, ensuring that their selection persists even if they refresh the page. This project will teach you advanced CSS techniques, JavaScript programming, and how to improve the user experience by storing data in the browser.

Recipe Book App

In this project, we're developing a recipe book application that features a variety of recipes obtained through a free recipe API. We need an API key to access this API. Each time the page is refreshed, a new set of recipes with distinct ingredients will be displayed. Additionally, a link is provided to access the recipe website.

Dice Roll Simulator

Welcome to the Dice Roll Simulator project. The final version of the project features a dice at the center of the screen and a "Roll dice" button. The button triggers an animation and generates a random number, which is displayed in the center of the dice when clicked, t. Additionally, the number is added to a history list. To achieve this, we used modern CSS to style the dice and added a JavaScript event listener to the button. The listener generates a random number, saves it to an array, and updates the history list.
