Introduction
Modern CSS provides powerful layout systems that allow developers to create responsive and dynamic web designs. Two of the most important layout tools are Flexbox and CSS Grid. While both are designed to solve layout problems, they serve different purposes and excel in different scenarios.
What is Flexbox?
Flexbox (Flexible Box Layout) is a one-dimensional layout model designed to align and distribute space among items in a container.
Flexbox Example
.container {
display: flex;
justify-content: space-between;
align-items: center;
}
Flexbox works great for navigation bars, aligning buttons, centering elements, and building simple layouts.
What is CSS Grid?
CSS Grid is a two-dimensional layout system that allows you to create complex grid-based designs with rows and columns.
Grid Example
.container {
display: grid;
grid-template-columns: repeat(3, 1fr);
gap: 20px;
}
Grid is ideal for full page layouts, dashboards, and complex responsive designs.
