Autoprefixer 
PostCSS plugin to parse CSS and add vendor prefixes to CSS rules using values from Can I Use. It is recommended by Google and used in Twitter and Alibaba.
Write your CSS rules without vendor prefixes (in fact, forget about them entirely):
::placeholder {
color: gray;
}
.image {
width: stretch;
}
Autoprefixer will use the data based on current browser popularity and property support to apply prefixes for you. You can try the interactive demo of Autoprefixer.
::-moz-placeholder {
color: gray;
}
::placeholder {
color: gray;
}
.image {
width: -webkit-fill-available;
width: -moz-available;
width: stretch;
}
