Align Buttons Side by Side Bootstrap

Question

I am trying to align my two bootstrap buttons side by side (horizontally), right now they are aligned one on top of another (vertically). I have found a few questions on here, but still can't seem to get it right...

I will post my code below:

<div class="row">
    <div class="col-sm-12">
         <asp:Button ID="btnSearch" runat="server" Text="Search" CssClass="btn btn-primary btn-md center-block" Style="width: 100px; margin-bottom: 10px;" OnClick="btnSearch_Click" />
         <asp:Button ID="btnClear" runat="server" Text="Clear" CssClass="btn btn-danger btn-md center-block" Style="width: 100px;" OnClick="btnClear_Click" />
     </div>
</div>

Answer 1

1) use display: inline-block

#btnSearch,
#btnClear{
    display: inline-block;
    vertical-align: top;
}

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css" rel="stylesheet"/>
<div class="row">
    <div class="col-sm-12 text-center">
        <button id="btnSearch" class="btn btn-primary btn-md center-block" Style="width: 100px;" OnClick="btnSearch_Click" >button</button>
         <button id="btnClear" class="btn btn-danger btn-md center-block" Style="width: 100px;" OnClick="btnClear_Click" >button</button>
     </div>
</div>

or

2) remove class .center-block

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css" rel="stylesheet"/>
<div class="row">
    <div class="col-sm-12 text-center">
        <button class="btn btn-primary btn-md">button</button>
        <button class="btn btn-danger btn-md">button</button>
     </div>
</div>
