place 1 label top, 1 input bottom and 2 buttons left

Question

I would like to place 1 label at the top of an Input with two centered buttons (inside a div) on the right.

for the moment my code isn't flexible and I can't easily use my class anywhere on my webpage as It is strongly dependent the #.bu-container height that is far more large than it should be. Also I'm not sure to have a good result when resizing even more on different browsers.

Thanks in advance for your replies,

Here is my erroneous code:

#position {
  height: 500px;
}
.bu-container {
  margin: 10px;
  display: block;
  float: left;
  height: 50px;
  width: 400px;
  overflow: hidden;
}
.bu-container input {
  float: left;
}
.bu-container .bu {
  float: right;
  top: 0px;
  right: 50px;
  padding: 1px;
}
.bu-container button {
  height: 10px;
  display: block;
}

<div id="Position">
  <span class="bu-container">
             <span class="bu"> <button></button> <button></button> </span>
  <label>Height</label>
  <input id="LHeight" min="0" type="number" value="">
  </span>
  <span class="bu-container">
                <span class="bu"> <button></button> <button></button> </span>
  <label>Width</label>
  <input id="LWidth" min="0" type="number" value="">
  </span>
  <span class="bu-container">
                <span class="bu"> <button></button> <button></button> </span>
  <label>X</label>
  <input id="x" min="0" type="number" value="">
  </span>
  <span class="bu-container">
            <span class="bu"> <button></button> <button></button> </span>
  <label>Y</label>
  <input id="y" min="0" type="number" value="">

  </span>
</div>
