Tribute Page - Feedback (+/-) appreciated

[KarenWangari2017]

Hey guys!

Just finished my tribute page:
https://codepen.io/KarenWangari2017/full/gOOYLKW

Would love to get any pointers on how I did it.

New to coding in HTML/CSS, so if there’re ways I would have tidied up my code: I am all ears.

Thanks in advance.

you don’t need the extra - before it.
our extra dot like .75 unlese it is 0.75 but do add the 0 then it makes it more pleasant to read.

Done & dusted
