Selenium Grid is a server that allows tests to use web browser instances running on remote machines. With Selenium Grid, one server acts as the central hub. Tests contact the hub to obtain access to browser instances. The hub has a list of servers that provide access to browser instances (WebDriver nodes), and lets tests use these instances.
For example, required elements might be preceded with an asterisk, elements with invalid data might acquire a red border, and so on. With this approach, users actually benefit from seeing many input elements at once — they can enter data in a way that makes sense to them, instead of having all the other unrelated elements blocked until a ...

While most are able to support common browser features (HTML parsing, cookies, XHR, some JavaScript, etc.), they do not render the DOM and have limited support for ...

[73] [better source needed] In the simple, general case, the extent of an element is indicated by a pair of tags: a "start tag" < p > and "end tag" </ p >. The text ...
Oracle APEX is a low-code development platform, a type of environment that can trace their origins to fourth-generation programming languages and rapid application development (RAD) tools. APEX allows users to build web applications with a "no code" graphical user interface. However, when the requirements are more complex, APEX allows the ...
Meta elements provide information about the web page, which can be used by search engines to help categorize the page correctly. They have been the focus of a field of marketing research known as search engine optimization (SEO), where different methods are used to provide a user's website with a higher ranking on search engines. Prior to the ...
