In web development, the terms “server-side” and “client-side” refer to the locations where application code runs.
When code, such as JavaScript, runs server side, all the work happens on the website’s server. The page is built, your login is checked, and data is pulled before anything appears in your browser.
Client side means that code, usually HTML, CSS, and JavaScript, runs in the user’s browser after the page loads. The client side is used to handle interactions, such as drop-down menus, form validation, animations, and content updates without reloading the page.
