Posted on September 3rd, 2024 by Quertime Team in Web Browsers

Unlike the standard computers we used in the good old days, now we have many types of devices such as laptops, tablets, netbooks, and smartphones which can be used to access Internet. Each device will have its own screen size, resolution and this makes the web design process more difficult than before. Web developers and designers have to make sure their websites or online applications compatible with most of the possible screen resolutions.

It’s unlikely to test designs in all of the Internet-capable devices, but what developers can do is to resize the browser dimension as per the screen size of a particular device.
