Thanks for correcting me on the subject, but i would also like to you about a website that did wrong calculations in regards to the px to em's calculation. This link here was the cause of my problems, my you would also like to know that. so here it is: http://pxtoem.com/ and later i discovered a working one when things got gowing for me, but then me and my cousent had slow networking as a problem, so the browser yammed and I could finish the challenge due to it. The working one was: http://www.w3schools.com/cssref/css_pxtoemconversion.asp

Do you need me to explain how I got to the answer or why the website may have been wrong?
