How to change the background color of text boxes?

Is there anyway to change the background color of a text box?  Not a header box but a text box?

Thanks!

You may change the  background color with the following CSS code: 

#id {

    background: orange;

}

Replacing the id with the element id and the orange color with the background color you want to have. Here's an image that will help you finding the element id:

I hope this helps. 

Where do I find the element ID once I hit inspect? A ton of coding popped
up when I hit inspect.

When you inspect an element of a site, a console menu will appear like the one in my colleague's screenshot. You'll need to make sure that the "Element" tab is selected.

Once you change the tab to "Elements" tab, you should see the list of HTML codes. Please take note of the #3 arrow in the screenshot where it says id="input_30", that would the field id of the hovered field (Short text field) in my colleague's example.

I hope that explains it, but let us know if you have further questions.
