How to insert white box on image banner

[sosober]

In my shop (0byf0v-34.myshopify.com; password: mohwhi) I'd like to put a white box on the image banner that will stay under the heading and button and that will be full page width.

The heading and button should be 2e2e2e and centered.

Also check if I have to use also a responsive code.

Thank you in advance!

Hi,

Hope this will help

- sections/banner.liquid or sections/image-banner.liquid need add code

Code example

<div class="white-box">
  <h1>Your Heading Text</h1>
  <a href="#" class="banner-button">Your Button</a>
</div>

- Add css for style
