CSS Max-Width - Detailed Overview

Introduction to CSS Max-Width

The CSS max-width property sets the maximum width of an element. It ensures that the element does not exceed a specified width, even if the content is larger. This is useful for responsive design and controlling element dimensions.

Fixed Max-Width

Setting a fixed maximum width for an element:

.max-width-example {
    max-width: 300px;
    background-color: #d0f0c0;
    padding: 10px;
    border: 1px solid #ddd;
}

This box has a maximum width of 300px. If the container is wider than 300px, the box will not stretch beyond this width.

Responsive Images

Using max-width: 100% for responsive images:

.responsive-image {
    max-width: 100%;
    height: auto;
}

Placeholder Image

This image will scale down to fit its container but will not exceed its original dimensions.

Container with Max-Width

Applying max-width to a container to limit its width:

.container {
    max-width: 800px;
    margin: 0 auto;
    padding: 20px;
    background-color: #fff;
    border-radius: 10px;
    box-shadow: 0 0 10px rgba(0, 0, 0, 0.1);
}

This container has a maximum width of 800px. It will center itself within the viewport.
