Stuck with elements- help plz!

Hi Im struggling with this task. I am unsure as to where to place my “black-mask” element. Although my div elements look ok. I’m not placing them in the right places. If anyone could explain .


  **Your code so far**
/* file: index.html */
<!DOCTYPE html>
  <meta charset="utf-8">
  <title>Picasso Painting</title>
  <link rel="stylesheet" href="./styles.css" />
  <link rel="stylesheet" href="">

  <div id="back-wall"></div>
      <div class="characters">
        <div id="offwhite-character">
          <div id="white-hat"></div>

          <div class="eyes left"><div>
            <div class-"eyes right"></div>



          <div id="gray-instrument"></div>
          <div id="tan-table"></div>

/* file: styles.css */
body {
background-color: rgb(184, 132, 46);

#back-wall {
background-color: #8B4513;
width: 100%;
height: 60%;
position: absolute;
top: 0;
left: 0;
z-index: -1;

The starting code of this step has the black-mask element in place already. You must have deleted it by accident.
