The text-rendering property does not exist: optimizeLegibility

1) -webkit-min-device-pixel-ratio property does not exist for media screen) {body {text-rendering: auto; }}

2) erroneous Property: padding -1px Negative values are not allowed: 13px 0 0 -1px

3) The zoom property does not exist: 1

4) The property pointer-events does not exist: none

I can not find anywhere coment do about it

Is this possible? and if so, how?
