I pasted the ad banner in footer, how can I align it in the centre please?

Thank you

Hey there

I hope you are well today and thank you for your question.

You can try achieving this by adding the following CSS code in the Custom CSS option of your theme on the below path.

Admin Area -> Appearance -> Customize -> Additional CSS

/*center banner */
div#div-gpt-ad-1503326391289-0 {
    width: 100%;
    margin: 0 auto;

Best Regards,
