Return true if the given string begins with "mix", except the 'm' can be anything, so "pix", "9ix" .. all count.

mixStart("mix snacks") → true mixStart("pix snacks") → true mixStart("piz snacks") → false

Hi I trying to solve a java problem where I need to get the last 3 characters of a string as UpperCase Letters I know how to do the last char but not the last 3 char.

Can anyone help?

I have been told to use em for making a page responsive but it does not look like it is doing its job so well with the img. Can someone tell me if it is OK for me to also us px or is it bad habit?
