CSS Change td size

I am trying to create a nice looking table. I found a template and I want to modify it. The problem is that if I want to modify the font size of the top headers, the ones inside "head_nav" like this : #head_nav th{ font-size: 30px;} nothing happens. Am I doing something wrong? Also I want to make the data "TD" a square size, not rectangle, so I tried this: tr, td{ width: 100%; height:100%;} but again nothing happens.

This is my code : 

<!doctype html>
<html>
<head>
    <title>Timetable</title>
    <style type="text/css">
    body
    {
        font-family: arial;
    }

    th,td
    {
        margin: 0;
        text-align: center;
        border-collapse: collapse;
        outline: 1px solid #e3e3e3;
    }

    td
    {
        padding: 5px 10px;
    }

    th
    {
        background: #666;
        color: white;
        padding: 5px 10px;
    }

    td:hover
    {
        cursor: pointer;
        background: #666;
        color: white;
    }
    </style>

</head>

<body>
    <table width="80%" align="center" >
    <div id="head_nav">
    <tr>
        <th>Time</th>
        <th>Monday</th>
        <th>Tuesday</th>
        <th>Wednesday</th>
        <th>Thrusday</th>
        <th>Friday</th>
        <th>Saturday</th>
    </tr>
    </div>  
    
        <tr>
            <th>10:00 - 11:00</th>
            
                <td>Physics-1</td>
                <td>English</td>
                <td title="No Class" class="Holiday"></td>
                <td>Chemestry-1</td>

                <td>Physical</td>
            </div>
        </tr>
    
        <tr>
            <th>11:00 - 12:00</td>

            </div>
        </tr>
    
        <tr>

Your code is invalid, try this.

 table tr:first-of-type

Don't insert table elements in divs, either use specific selectors, or give classes/id's to your td/tr's.

As you've also been told, inline CSS is a bad practice, so move it in a separate CSS file.

  body {
      font-family: arial;
  }
  th, td {
      margin: 0;
      text-align: center;
      border-collapse: collapse;
      outline: 1px solid #e3e3e3;
  }
  td {
      padding: 5px 10px;
  }
  th {
      background: #666;
      color: white;
      padding: 5px 10px;
  }
  td:hover {
      cursor: pointer;
      background: #666;
      color: white;
  }
  table tr:first-of-type {
      font-size:30px;
  }
<title>Timetable</title>
<table width="80%" align="center">
    <tr>
        <th>Time</th>
        <th>Monday</th>
        <th>Tuesday</th>
        <th>Wednesday</th>
        <th>Thrusday</th>
        <th>Friday</th>
        <th>Saturday</th>
    </tr>
    <tr>
        <th>10:00 - 11:00</th>
        <td>Physics-1</td>
        <td>English</td>
        <td title="No Class" class="Holiday"></td>

            <td>Math-2</td>
