html2canvas
html2canvas is a unique script that enables users to capture screenshots of websites or specific portions of the website on any modern browser. Screenshots, however, may be less accurate than the actual representation because of the usage of DOM, which generates the screenshot by gathering all the data on the page.
When the user invokes the script, it travels through the DOM of the specified page and collects data on all the objects present on it. This data is used to produce a replica of the page, meaning it doesn’t snap a picture but creates a likeness based on the attributes fetched from the DOM.
A few attributes aren’t supported by the script and may not make it to the final screenshot. Users can check the names of supported attributes by visiting the Features section. html2canvas can run seamlessly on several browsers, including Safari, Firefox, IE9, Chrome, Edge, and Opera.
