Right now, the industry standard for every website should be to have a responsive website, meaning the design and layout should “respond” to the browser size and format to look its best for that size and device. For instance, if you look at a site on a desktop computer, it should be readable and formatted to make the most of the browser size, but when viewed on a tablet or mobile device, it should reformat to better fit that devices size to make the text readable and the buttons clickable.
