For this website, I used heavily on the div tags to separate the content in my webpage. While the outward appearance does not seem to change if I remove those div tags, this is more a organization purpose. If I choose to change a certain part of the my web page, I will know which specific section through the use of the div tag.
Furthermore, changing the size of an image can be done through the adding extra elements within the img tag. While I have downsized the image on my webpage, I had to find the right ratio of height and width. If one of the other is too long or too short, then the image itself will appear disproportionate.
