element it represents.
A string indicating the full URL of the image currently visible in the <img>
element represented by the HTMLImageElement

and/or HTMLImageElement.srcset
properties. currentSrc
lets you determine which image from the set of provided images was selected by the browser.
In this example, two different sizes are provided for an image of a clock. One is 200px wide and the other is 400px wide. The sizes
attribute is provided to indicate that the image should be drawn at 50% of the document width if the viewport is under 400px wide; otherwise, the image is drawn at 90% width of the document.
