How to align multiple buttons inside a row in html?

Question

I am working on aligning two buttons to the middle of the row which is just below a table in the form.

But the alignment of buttons is vertical now. How do I make them horizontal and to the middle.

This is how it is being displayed now

For Joykal Infotech reference in IE after adding vendor prefixes

I want to align them properly to the middle of the row and the buttons should be on same axis. Return to Login should not be in multiple lines.

Here's what I tried.

div.blueButton { /* Blue Button sized for submit */
            position:relative;
            margin:0;
            background:transparent url('../images/btn_blue_back.gif') repeat-x;
            color:white;
            padding:0 4px 6px 4px;
            text-align:center;
            width:45px;
            margin-left:520px;
        }
        div.blueButton_left {
            background:transparent url('../images/btn_blue_l.gif') no-repeat left;
            width:7px; height:22px;
            position:absolute;
            top:-2px; left:-2px;    
        }
        div.blueButton_right {
            background:transparent url('../images/btn_blue_r.gif') no-repeat right;
            width:7px; height:22px;
            position:absolute;
            top:-2px; right:-3px;   
        }

a.button, .button {
            width:auto;
            padding:0; margin:0 0 0 0;
            background:#005499;
            font-size:11px; font-weight:bold; color:white; text-decoration:none;
            cursor:pointer;
        }

<div>
<div class="blueButton">
<div class="blueButton_left"></div>
<div class="blueButton_right"></div>
<a href="" onclick="javascript:forgotUsername();return false;" class="button" onblur="javascript:f_setfocus();">Return to LogIn</a>
</div>
<div class="blueButton">
<div class="blueButton_left"></div>
<div class="blueButton_right"></div>
<a href="" onclick="javascript:forgotUsername();return false;" class="button" onblur="javascript:f_setfocus();">Continue</a>
</div>
</div>

Hope, this might help I have used a wrapper above both the buttons and provided display: flex; and justify-content:center and also removed the fixed width and margin given to div.bluebutton

And do checkout flexbox

Update - vendor prefixes added

.wrap {
  -webkit-display: flex;
  -ms-display: flex;
  -o-display: flex;
  display: flex;
  -webkit-justify-content: center;
  -ms-justify-content: center;
  -o-justify-content: center;
  justify-content: center;
}
div.blueButton {
  /* Blue Button sized for submit */
  position: relative;
  margin: 0;
  background: transparent url('../images/btn_blue_back.gif') repeat-x;
  color: white;
  padding: 0 4px 6px 4px;
  text-align: center;
}

div.blueButton_left {
  background: transparent url('../images/btn_blue_l.gif') no-repeat left;
  width: 7px;
  height: 22px;
  position: absolute;
  top: -2px;
  left: -2px;
}

div.blueButton_right {
  background: transparent url('../images/btn_blue_r.gif') no-repeat right;
  width: 7px;
  height: 22px;
  position: absolute;
  top: -2px;
  right: -3px;
}

a.button,
.button {
  width: auto;
  padding: 0;
  margin: 0 0 0 0;
  background: #005499;
  font-size: 11px;
  font-weight: bold;
  color: white;
  text-decoration: none;
  cursor: pointer;
}

<div class="wrap">
  <div class="blueButton">
    <div class="blueButton_left"></div>
    <div class="blueButton_right"></div>
    <a href="" onclick="javascript:forgotUsername();return false;" class="button" onblur="javascript:f_setfocus();">Return to LogIn</a>
  </div>
  <div class="blueButton">
    <div class="blueButton_left"></div>
    <div class="blueButton_right"></div>
    <a href="" onclick="javascript:forgotUsername();return false;" class="button" onblur="javascript:f_setfocus();">Continue</a>
  </div>
</div>
