Question

I have a problem, and I made this test code to show you my problem.

• HTML code: https://i.stack.imgur.com/7qlZx.png
• Javascript code: https://i.stack.imgur.com/DYvuq.png

What I want to do is to change the styles of the id. But for some reason it doesn’t work.

I don’t know what’s happening and I really need your help. Thanks.

Answer 1

In your original code you are incorrectly referring to the JavaScript properties as methods…

// ORIGINAL/INCORRECT CODE
// x.style.fontSize('20px');
// x.style.fontFamily('arial');
// x.style.color('#008080');
// x.style.border('10px solid #000');

Corrected…

// CORRECTED
// These are properties, NOT methods.
x.style.fontSize = '20px';
x.style.fontFamily = 'arial';
x.style.color = '#008080';
x.style.border = '10px solid #000';
