!Expected end of value but found line-height:

Hi,

I’m getting an error message from Additional CSS customizer.

!Expected end of value but found line-height:

/* large intro text for services and work */
.largetextgreen {
font-size: 26px;
font-weight: 400
line-height: 1.8em;
text-align: left;
color: #1f9e49;
}
/* ends */

/* large intro text for services and work */
.largetext {
font-size: 26px;
font-weight: 400
line-height: 1.8em;
text-align: left;

}
/* ends */

Not sure why looks okay in Brackets. Any ideas or recommendations.

Thanks
Scott
