I have a button like the following:
CSS
.Btns {
        width:200px;              
        height:75px;
        background-color:lightblue;
        color:black;
        font-weight:bold;
    }
HTML:
<button id="btnProduct" type="button" class="Btns" >
JQUERY:
$("#btnProduct").html('<span style="background-color:red;width:100px">Production:</span></br></br><span class="blue">55</span>');
I want upper part of my button to be red,as you see in my code I gave my span 100% but still has not filled the whole of upper part of button.
$("#btnProduct").html('<span style="background-color:red;width:100px">Production:</span></br></br><span class="blue">55</span>');
.Btns {
  width: 200px;
  height: 75px;
  background-color: lightblue;
  color: black;
  font-weight: bold;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<button id="btnProduct" type="button" class="Btns">
 
</button>
