Editing CSS of Agoda Search widget

Hi there, I am trying to edit the height of an Agoda search widget however it doesn’t’ seem to be responding. You can see it on the sidebar of https://www.planitnz.com.

I tried to edit it from:

#AgodaSearchBox {
background-color: transparent;
background-position: -36px 0;
background-repeat: no-repeat;
float: left;
height: 223px;
margin: 0;
padding-top: 0px;
text-align: center;
width: 279px;
position: relative;
left: 0px;
font-family: tahoma;
font-size: 13px;
bottom: 0;
}

to

#AgodaSearchBox {
background-color: transparent;
background-position: -36px 0;
background-repeat: no-repeat;
float: left;
height: 205px;
margin: 0;
padding-top: 0px;
text-align: center;
width: 279px;
position: relative;
left: 0px;
font-family: tahoma;
font-size: 13px;
bottom: 0;
}

but it doesn’t seem to change. Any idea what I could be doing wrong?
