How to avoid div height from master page

<pre> Hello All,

Greetings for the day!

Am sure it has been asked earlier, but i couldn't find the better solution else where.

Well, there is a Div ID "#ctl00_ctl00_CPMain_Tabs_pnl1111_Fp1_rowHeader" with some inline height, and in Master page also this ID has height defined.
I need to diable(or set "auto !important") both the height as it's adding some extra height to the grid.

below is Data.Master code

<pre lang="ASP.NET">#ctl00_ctl00_CPMain_Tabs_pnl1111_Fp1_rowHeader {
            height: 630px !important;
        }

i made the inline height "auto !important" by writing below code

$('#ctl00_ctl00_CPMain_Tabs_pnl1111_Fp1_rowHeader').css("height", "auto !important");

I am unable to avoid height which is getting applied from Master page.

Thanks,
Alin

if (("#ctl00_ctl00_CPMain_Tabs_pnl1111_Fp1_rowHeader").height == "630px !important") {
                    $('#ctl00_ctl00_CPMain_Tabs_pnl1111_Fp1_rowHeader').css("height", "auto !important");
                }
