Experiment with the app

Hi guys just wanted to share my program. Dave McFarland asked us to experiment with the app in the Select page element by ID lesson.

video link: https://teamtreehouse.com/library/select-a-page-element-by-its-id

Just wanted to share my code.

The first input changes the color the second changes the font size. It accepts all the units, px, em, rem,%.

<!DOCTYPE html>
<html>
  <head>
    <title>JavaScript and the DOM</title>
    <link rel="stylesheet" href="css/styles.css">
  </head>
  <body>
    <h1 id="myHeading">JavaScript and the DOM</h1>
    <p>Making a web page interactive</p>
    <input type="text" name="" value="" id="myTextInput">
    <button type="button" name="button" id="myButton">Change Headline color</button>
    <input type="text" name="" value="" id="changeStyle">
    <button type="button" name="button" id="fontSize">Change font size</button>
    <button type="button" name="button" id="reset">Reset Button</button>

    <script src="js/app.js"></script>
  </body>
</html>

const myHeading = document.getElementById('myHeading');
const myButton = document.getElementById('myButton');
const myTextInput = document.getElementById('myTextInput');
const reset = document.getElementById('reset');
const changeStyle = document.getElementById('changeStyle');
const fontSize = document.getElementById('fontSize');

myButton.addEventListener('click', () => {
  myHeading.style.color = myTextInput.value;
});

fontSize.addEventListener('click', () => {
  myHeading.style.fontSize = changeStyle.value;
});

reset.addEventListener('click', () => {
  myHeading.style.color = '#363636';
  myHeading.style.fontSize = '2em';
});
