A fixed-width layout method specifies exact pixel values for widths. This approach does not adapt to different screen sizes, leading to images rendering too small or too large on various devices.

Fixed Width Layout:

Definition: Uses specific pixel values for the width of elements.

Example:

container {

width: 800px;

}

Issues:

Lack of Flexibility: Does not scale with the size of the viewport, causing images and other elements to appear incorrectly sized on different screen sizes.

Comparison:

Fluid/Liquid: Adapts to the screen size using percentages or other relative units.

Relative Width: Also adapts using units like em or %.
