CSS Color Palette: How to Choose and Combine Colors Effectively

Tue, 16 Sep 2025 15:13:06 +0200

I. Why a Well-Thought CSS Color Palette Matters

A well-designed palette ensures visual consistency, reinforces brand identity, and provides a smooth user experience. It simplifies code maintenance, avoids redundant colors, and allows for easy theme adaptation (light/dark). Following best practices also enhances accessibility: sufficient contrast, and visual cues beyond just color.

II. Understanding CSS Color Formats (hex, RGB, HSL, keywords)

CSS offers several formats to define colors:

Organizing Your Frontend Project: Clean and Simple Folder Structure

Fri, 05 Sep 2025 12:09:45 +0200

I. Why Organize Your Frontend Project?

When you’re starting with web development, it’s common to place all your files in one folder. However, good organization quickly becomes essential as the project grows, whether for:

Navigating your codebase easily.
Collaborating effectively with other developers.
Making maintenance and updates easier.
Saving time in the long run.

II. Recommended Structure for a Simple Project

Here’s a classic, clean structure for an HTML/CSS/JS project without a framework:

Understanding the CSS Box Model

Mon, 04 Aug 2025 16:09:45 +0200

I. What is the CSS Box Model?

In CSS, every HTML element is treated as a rectangular box. This is called the box model.

The box model defines how an element’s total size is calculated, and how it interacts with surrounding elements.

An HTML element consists of 4 main areas:

+-------------------------------+
| margin (outer) |
| +-------------------------+ |
| | border (border) | |
| | +-------------------+ | |
| | | padding (space) | | |
| | | +---------------+ | | |
| | | | content | | | |
| | | +---------------+ | | |
| | +-------------------+ | |
| +-------------------------+ |
+-------------------------------+

II. The 4 Parts of the Box Model

1. `content`

The actual content of the element (text, image, button…).

Responsive vs Adaptive: Two Strategies, One Common Goal

Mon, 28 Jul 2025 12:14:54 +0200

I. Introduction

Responsive design and adaptive design are two widely used approaches to creating web interfaces that are accessible across a variety of devices. In a world where screen size diversity — from smartphones to 4K monitors — is the norm, understanding the differences between these strategies is essential for any frontend developer or designer. This article offers a clear, comparative, and well-documented overview of both methodologies, including concrete use cases and practical recommendations.

Optimizing Flutter Performance: build(), keys, and const Widgets

Tue, 15 Jul 2025 09:24:42 +0200

This article proposes performance improvements by focusing on three fundamental aspects:

The build() cycle
Keys
Const widgets

I. The build() cycle: understanding to optimize

The build() process is at the core of rendering in Flutter. When a state changes or a widget is rebuilt, the build() method is called. Mismanaging this method can cause significant slowdowns.

A. When is build() triggered?

During the first widget creation.
When calling setState().
When a parent widget is rebuilt.

B. Techniques to reduce the build() impact

Use const in the constructor: Creates immutable instances.
Break down the build: Split the UI into subcomponents to reduce the impact zone.
Avoid heavy calculations in build(): Delegate tasks to pre-computed functions or separate methods.

Example: Optimization with subcomponents

Flutter & Redux: A Well-Organized Recipe with Dispatch

Sun, 22 Jun 2025 19:38:55 +0100

I. Introduction to Redux in Flutter

Inspired by the unidirectional data flow model, Redux allows you to centralize the application’s state and modify it through clear, predictable, and testable actions.

The core of Redux is based on three concepts:

Store: the global state.
Action: an event describing a change.
Reducer: a function that transforms the state based on the action.

The goal of this article is to understand how to use dispatch with Redux in Flutter, with a simple, educational, and rigorous approach.

Flutter Hot Reload: Why Is It So Fast?

Mon, 19 May 2025 13:45:30 +0200

I. What Is Hot Reload in Flutter?

Hot reload is a Flutter feature that allows developers to quickly reload modified code in a running app without a full restart. This operation retains the current app state, unlike a traditional restart.

Key benefits:

Saves time when developing UIs.
Maintains state: ideal for testing changes without re-navigating.
Shorter development cycles.

Flutter supports hot reload thanks to the Dart engine architecture, which allows dynamic code injection into a running application.

Flutter for True Beginners: What It Is, What It’s For, and How to Try It

Mon, 12 May 2025 10:10:48 +0200

I. What is Flutter?

Flutter is an open-source framework developed by Google, designed to build native user interfaces for Android, iOS, Web, and desktop from a single codebase. It uses the Dart language and allows developers to build smooth, high-performance, and visually appealing apps.

Flutter stands out thanks to its integrated rendering engine and ability to display animations at 60 fps or higher. It doesn’t rely on native platform UI components, which ensures visual consistency across platforms.
