title: How can I do a search textbox?
body: <p>I wish to do a search box just like this:</p>
  
  <p><img src="https://i.stack.imgur.com/zsd92.png" alt="Wallbase.cc&#39;s search box"></p>
  
  <p>Analyzing the code, I saw that it uses a image as background and repeats it horizontally.</p>
  
  <p>But I have no idea on how will I transform this as a input field.</p>
  
  <p>Please help me?</p>
