Help - How do you make an image responsive in Gravity forms?

How do you make an image in Gravity forms responsive? I added an image and it looked great on a desktop but when I viewed it in my mobile phone it was too small.

How can I make an image in Gravity forms responsive so that it appears much bigger on a mobile device?

Many thanks

In the same way that you added your own HTML tag to include the image, you will need to add also your own CSS to your site to make it responsive.

For example, by adding a CSS class name to your HTML img tag and adding your custom CSS to the site with the CSS properties for that CSS class.

The following links may help you with the CSS:

Thanks again Samuel. I might also use a Lightbox plugin to increase the size of the Pop up image.
