2. The Sales Page Course Images:
✿ Image were more than 8 Megabyte in size which is the cause of slow loading of the page. I reduced it 2.5 Megabyte which makes the pages load faster.
✿ I use a Navy blue Bar behind the Navigation menu so the texts are clearly visible on every image. You user avatar is not that important because everyone will be seeing their own avatar.
✿ I used the website address on every image to get them visit the website. Call to action.
