<!-- Html is neat. Anyways have 1/3 of the flag: picoCTF{tru3_d3 -->

<!doctype html>
<html>
  <head>
    <title>My First Website :)</title>
    <link href="https://fonts.googleapis.com/css?family=Open+Sans|Roboto" rel="stylesheet">
    <link rel="stylesheet" type="text/css" href="mycss.css">
    <script type="application/javascript" src="myjs.js"></script>
  </head>

  <body>
    <div class="container">
      <header>
    <h1>Inspect Me</h1>
      </header>

      <button class="tablink" onclick="openTab('tabintro', this, '#222')" id="defaultOpen">What</button>
      <button class="tablink" onclick="openTab('tababout', this, '#222')">How</button>

      <div id="tabintro" class="tabcontent">
    <h3>What</h3>
    <p>I made a website</p>
      </div>

      <div id="tababout" class="tabcontent">
    <h3>How</h3>
    <p>I used these to make this site: <br/>

      </div>

    </div>

  </body>
</html>

Next, We'll check source of CSS file. We'll see another comment '/ You need CSS to make pretty pages. Here's part 2/3 of the flag: t3ct1ve_0r_ju5t /'

div.container {
    width: 100%;
}

header {
    background-color: black;
    padding: 1em;
    color: white;
    clear: left;
    text-align: center;
}

body {
    font-family: Roboto;
}

h1 {
    color: white;
}

p {
    font-family: "Open Sans";
}

.tablink {
    background-color: #555;
    color: white;
    float: left;
    border: none;
    outline: none;
    cursor: pointer;
    padding: 14px 16px;
    font-size: 17px;
    width: 50%;
}

.tablink:hover {
    background-color: #777;
}

.tabcontent {
    color: #111;
    display: none;
    padding: 50px;
    text-align: center;
}

#tabintro { background-color: #ccc; }
#tababout { background-color: #ccc; }

/* You need CSS to make pretty pages. Here's part 2/3 of the flag: t3ct1ve_0r_ju5t */

And finally, we'll check JS file. We'll see another comment '/ Javascript sure is neat. Anyways part 3/3 of the flag: _lucky?9df7e69a} /'

function openTab(tabName,elmnt,color) {
    var i, tabcontent, tablinks;
    tabcontent = document.getElementsByClassName("tabcontent");
    for (i = 0; i < tabcontent.length; i++) {
    tabcontent[i].style.display = "none";
    }
    tablinks = document.getElementsByClassName("tablink");
    for (i = 0; i < tablinks.length; i++) {
    tablinks[i].style.backgroundColor = "";
    }
    document.getElementById(tabName).style.display = "block";
    if(elmnt.style != null) {
    elmnt.style.backgroundColor = color;
    }
}

window.onload = function() {
    openTab('tabintro', this, '#222');
}

/* Javascript sure is neat. Anyways part 3/3 of the flag: _lucky?9df7e69a} */
