Why take this course?
Quick load times and responsive content leads to higher conversions. There's much more to images on the web than <img>. Attributes like srcset, markup techniques using CSS, fonts, and inline images, and the brand new <picture> element are now available to help you create the best possible experience for your users. This course will help you ensure that you deliver the highest quality images with the fewest possible bytes.
Learn with the best.
