I just have done my html file and now trying to do my css file but i get 3 errors all saying Property hight doesn't exist but i do have hights why is this.

link to code

Lines 5, 57 and 67 have an incorrect spelling of height.

Change from hight to height.

You might also want to run your code through the checker at the following link:

as the code appears to be raising a number of issues.
