Placeholder Styling

Hi. I’m trying to style the placeholder text on my contact form (see link in private data).

I have written the following CSS:

#home_contact input::-webkit-input-placeholder {
	color: #ffffff !important; {
	letter-spacing: 0.2em !important;
	text-transform: uppercase !important;
	text-align: left !important;
	-webkit-font-smoothing: antialiased !important;
	-moz-osx-font-smoothing: grayscale !important;
	font-family: 'Montserrat', sans-serif !important;
	font-weight: 200 !important;
	font-size: 12px !important;
}

#home_contact input:-moz-placeholder {
	color: #ffffff !important; {
	letter-spacing: 0.2em !important;
	text-transform: uppercase !important;
	text-align: left !important;
	-webkit-font-smoothing: antialiased !important;
	-moz-osx-font-smoothing: grayscale !important;
	font-family: 'Montserrat', sans-serif !important;
	font-weight: 200 !important;
	font-size: 12px !important;
}

#home_contact input::-moz-placeholder {
	color: #ffffff !important; {
	letter-spacing: 0.2em !important;
	text-transform: uppercase !important;
	text-align: left !important;
	-webkit-font-smoothing: antialiased !important;
	-moz-osx-font-smoothing: grayscale !important;
	font-family: 'Montserrat', sans-serif !important;
	font-weight: 200 !important;
	font-size: 12px !important;
}

#home_contact input:-ms-input-placeholder {
	color: #ffffff !important; {
	letter-spacing: 0.2em !important;
	text-transform: uppercase !important;
	text-align: left !important;
	-webkit-font-smoothing: antialiased !important;
	-moz-osx-font-smoothing: grayscale !important;
	font-family: 'Montserrat', sans-serif !important;
	font-weight: 200 !important;
	font-size: 12px !important;
}

but as you will see, a number of the properties are not showing up. Specifically:

• letter-spacing: 0.2em !important;
• text-transform: uppercase !important;
• text-align: left !important;

Can you help?
