Having continued to view this course I am now somewhat concerned that many technical aspects of what this tutor is promoting are totally wrong. My confidence in this course has now diminished to such an extent that I do not want to go further due to a lack of trust in what the tutor is promoting, here are just two examples:
Tutor states : AMP image width & height image attributes allow the browser to create place holders for images before they download they by stopping the movement of text when images are placed as part of AMP's image optimization.
FACT: see https://www.w3schools.com/tags/att_img_width.asp
As stated by the w3c:
Tip: Always specify both the height and width attributes for images. If height and width are set, the space required for the image is reserved when the page is loaded. However, without these attributes, the browser does not know the size of the image, and cannot reserve the appropriate space to it. The effect will be that the page layout will change during loading (while the images load). Which as we all know has nothing to do with AMP.
Tutor often refers to AMP's image optimization in fact constantly in one video on AMP images.
FACT : AMP does not optimize images see : http://stackoverflow.com/questions/34385509/how-does-amp-html-support-image-optimization + many other web sources. The srcset attribute referred to is a HTML5 attribute & nothing to do with AMP.
The above are just two of many examples that I could give.
Can I claim my money back for this course, if so then please advise.
