Another quick CSS tweak...

Unsure what command is needed in child css to remove the following from parent css (bolded line the one I need removed):

select,
input[type="text"],
input[type="password"],
input[type="email"] {
-moz-box-sizing: border-box;
-moz-border-radius: 2px;
-webkit-box-sizing: border-box;
-webkit-border-radius: 2px;
-webkit-box-shadow: 0 1px 0 #fff, inset 0 1px 1px rgba(0, 0, 0, 0.2);
-moz-box-shadow: 0 1px 0 #fff, inset 0 1px 1px rgba(0, 0, 0, 0.2);
box-shadow: 0 1px 0 #fff, inset 0 1px 1px rgba(0, 0, 0, 0.2);
background-color: #fff;
box-sizing: border-box;
border: 1px solid #aaa;
border-bottom-color: #ccc;
border-radius: 2px;
margin: 0;
outline: none;
padding: 6px 8px;
vertical-align: middle;
width: 100%;
}

I tried this in child css, but didn't work:

select,
input[type="text"],
input[type="password"],
input[type="email"] {
-moz-box-sizing: none;
}

Thanks!
