<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<style type="text/css">
.text {
background-color: #343434;
}
span {
vertical-align: middle;
}
img {
vertical-align: middle;
}
button {
vertical-align: baseline;
}
</style>
</head>
<body>
<div class="text">
<span>1234</span>
<img src="./img/bs.jpg" >
<button type="button"></button>
</div>
</body>
</html>
