What does the alt="" stand for in the image tag?
<img Src="" alt="" />
The text in alt is displayed in browser if the browser failed to load the image or if image content is disabled on browser settings. Anyway, isn't it covered in HTML course already? alt : Alternative text to show instead of image.
It's also used by screen readers for the vision impaired. https://www.w3schools.com/tags/att_img_alt.asp
text displayed during mouse-hover I guess.
