tabindexkäytössä

The term "tabindexkäytössä" appears to be a portmanteau of the English word "tabindex" and the Finnish word "käytössä," which translates to "in use" or "enabled." Therefore, "tabindexkäytössä" likely refers to the state or application of the tabindex attribute within web development.

The tabindex attribute in HTML is used to specify the tab order of elements within a document. Elements with a positive tabindex value are focusable and will be visited in the order specified by the numerical value. Elements with a tabindex of 0 will be focusable and visited in the order they appear in the DOM. Elements with a tabindex of -1 are not directly focusable via keyboard navigation but can be programmatically focused using JavaScript.

When tabindexkäytössä is discussed, it implies that the tabindex attribute is actively being used to manage keyboard navigation through interactive elements on a webpage. This is crucial for accessibility, ensuring that users who rely on keyboard navigation can access and interact with all essential components of a website. Proper tabindexkäytössä allows for a logical and predictable flow, improving the user experience for a wider audience. Incorrect or overuse of tabindex, especially with large positive values, can disrupt natural DOM order and create accessibility barriers.
