Frequently asked questions
What is viewport size?
The viewport is the visible area of a webpage in your browser. It changes based on your browser window size and does not include browser chrome (toolbars, scrollbars).
Why does browser size matter?
Responsive design requires your website to look good at all viewport sizes. Knowing the exact dimensions helps you test and debug media queries.
What is the difference between viewport and screen size?
Screen size is your monitor resolution. Viewport is the browser content area, which is smaller due to browser chrome, OS taskbar, etc.
