Not everyone uses a mouse to interact with a webpage, and even if they do, they might find it difficult to make precise movements or clicks. Blind users typically use a screen reader, which is keyboard-operated. Many people with physical disabilities use a keyboard or an input device that acts as a keyboard (such as speech input software or on-screen keyboard). Because of the many alternatives to using a mouse, it is important to ensure that a webpage can be operated using a keyboard. This includes ensuring that a keyboard can be used to tab through all links on a webpage.
Keyboard accessibility is determined by the source order of elements within the HTML code. Therefore, order your elements within the code in a way that would support a logical flow.
