// Google's Material design specs are in 'sp' or 'dp' which are not css units
// 'dp' is 'density independant pexels' and 'sp' is 'scale-independent pixels'
// (same as dp, but will be scaled by the user's font size preference)
// Android gives a 160dpi  base value to 'sp' and 'dp', but Google's examples seems to use 'sp' as 'px'
// We define a scaling factor in case we need to adjust
// 'sp' equals 1/16rem, wich represents 1 css pixel
// 'dp' is scale to 1 css-px according

// We assume users are setting browser's base font-size according to their needs
// The default rem size in use for most browsers is 16 css pixels
// Body font size is defined as 100%, so it won't changege users'settings
