title: How to make input and select to be same width in css
body: <p>In my page, there are several <code>input</code> and <code>select</code> tags.</p>
  
  <p>I use <code>width:100%;</code> to define their width, but the width in the browser is not <code>100%</code>.</p>
  
  <p>I used the debug tool in chrome, and found there is also useragent stylesheet styles applied.</p>
  
  <p>How can I make the width 100%?</p>
