Responsive images
The essence of responsive images is that they display correctly on every device, whether it is a mobile phone, tablet, or large-screen monitor.
Basic method: max-width and height
The most common solution is to adjust the width of images to the parent element with max-width: 100% and height: auto.
The following example shows how a simple image becomes responsive with CSS settings.
Advanced solution: picture and source
The picture and source elements allow us to load different images for different screen sizes or resolutions.
