Missing an Element or grabbed the wrong one?

I have tried many different ways to get the input selected even tried 'LI'.input or or mixture of that, unless its an event bubbling that I'm messing up?

index.html
<!DOCTYPE html>
<html>
    <head>
        <title>JavaScript and the DOM</title>
    </head>
    <link rel="stylesheet" href="style.css" />
    <body>
        <section>
            <h1>Making a Webpage Interactive</h1>

            <ul>
                <li>Item One: <input type="text"></li>
                <li>Item Two: <input type="text"></li>
                <li>Item Three: <input type="text"></li>

            </ul>
            <button>Save</button>
        </section>
        <script src="app.js"></script>
    </body>
</html>
app.js
let section = document.getElementsByTagName('section')[0];

section.addEventListener('click', (e) => {
  if (event.target.textContent == 'LI','input') {
  e.target.style.backgroundColor = 'rgb(255, 255, 0)';
  }
  });

You want to check to see if the tagName property of the target element is INPUT:

if (event.target.tagName == 'INPUT')
