Tạo terminal commands line với HTML/CSS

Trong bài viết này tôi sẽ giới thiệu tới các bước để tạo terminal commands line chỉ với HTML/CSS, kết quả như hình dưới đây :

Mã HTML

Cấu trúc HTML như sau, mình giải thích trong comment.

<!-- Menu terminal -->
<div class="terminal-menu">
  <div class="terminal-buttons terminal-close"></div>
  <div class="terminal-buttons terminal-minimize"></div>
  <div class="terminal-buttons terminal-zoom"></div>
</div>
<!-- Screen terminal -->
<div class="terminal-screen">
  <!-- Dòng 1--> 
  <p class="line1">&#91;&nbsp;&ldquo;I'm a web developer.&rdquo;,
      <span class="cursor1">_</span>
  </p>
  <!-- Dòng 2--> 
  <p class="line2">&nbsp;&nbsp;&ldquo;I'm a web designer.&rdquo;,
      <span class="cursor2">_</span>
  </p>
  <!-- Dòng 3--> 
  <p class="line3">&nbsp;&nbsp;&ldquo;Let's work together!&rdquo;&nbsp;&#93;
      <span class="cursor3">_</span>
  </p>
  <!-- Dòng 4--> 
  <p class="line4">>
      <span class="cursor4">_</span>
  </p>
</div>
