The “max-width” CSS property defines an element’s maximum width in absolute terms (pixels) or relative terms (ems, rems, percentages, viewport-height, or viewport-width). Width properties in CSS ensure elements, such as images, text boxes, and other containers don't extend beyond a set width limit, preventing content from overflowing or cutting off.
Limiting an element’s horizontal width helps adapt responsive content to different devices, screen sizes, and orientations, improving site readability. It does not, however, affect assets smaller than an element's maximum width.
Here’s an example code snippet of a CSS “max-width” property:
The container restricts the width to a maximum of 300 pixels, ensuring that the element won’t exceed this limitation, maintaining a uniform size.
