two errors in siteorigin css

I have two mistakes in my custom css but they work :-)
I know it is not a theme question but don’t know who to ask…

#footer-widgets .widget {
text-align: bottom; expected (left-right-center but found bottom)</li)
}
.sow-image-grid-wrapper img:hover{
opacity:0.5;
filter: alpha(opacity=50); /* For IE8 and earlier */ (expected funtion filter list but found Alpha opacity)
-webkit-transition: all 1s ease;
-moz-transition: all 1s ease;
-ms-transition: all 1s ease;
-o-transition: all 1s ease;
transition: all 1s ease;
}
