To center the main on the page using flexbox, add justify-content: center;
to the body.
give #imagemtopo a fixed padding value instead of a percentage value.
For a more responsive content replace the width of the main with max-with and height value with height: auto
Use rem or em as unit for the padding, margin, width and preferably rem for the font-size for more on this watch this https://youtu.be/N5wpD9Ov_To
