Align asp:Button above first column of the gridview below - html

Question

I have a styling problem
I am trying to align a button with the first column of a gridview which is right underneath.
Something like this:
I've done the following but obviously it will fail with different resolutions:
<div class="formsFormBlock">
<asp:Label ID="LblRecurError" runat="server" />
<div style="text-align: left; position: relative; left: -15%;">
<table style="border: 0">
<tr>
<td style="border: 0">
<asp:Button ID="btnRecur" runat="server" Text="Repeat" />
</td>
</tr>
</table>
</div>
<asp:GridView>
</asp:GridView>
How can i do this?
Addition:
the gridview doesn't have a cssclass but the div above has the following css attributes:
.formsFormBlock{clear:both;position:relative;border-bottom:1px solid #e8f1f7;padding:0.53em 0.83em}
.formsFormBlock .formsItemLabel{display:block;width:25%;float:left;position:relative}
.formsFormBlock .formsItemLabel em{position:absolute;/*right:1.66em*/color:#ff0000}
.formsFormBlock .formsFormBlockHint{color:#999;font-size:92%;}
#formsFormHd:after, .formsFormBlock:after{content:".";display:block;height:0;clear:both;visibility:hidden;}
#formsFormHd, .formsFormBlock{display:block;clear:both;}
*:first-child+html #formsFormHd, *:first-child+html .formsFormBlock{display:inline-block;}

<div id="container">
<div style="float: left; margin-bottom: 10px;">
<asp:Label ID="LblRecurError" runat="server" />
<br />
<asp:Button ID="btnRecur" runat="server" Text="Repeat" />
</div>
<div style="clear: left;">
<asp:GridView runat="server">
</asp:GridView>
</div>
</div>
