parallax effect

Is there any way to add a parallax effect on the service section items?

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

#services { 
    /* The image used */
    background-image: url("");

    /* Full height */
    height: 100%; 

    /* Create the parallax scrolling effect */
    background-attachment: fixed;
    background-position: center;
    background-repeat: no-repeat;
    background-size: cover;

Best Regards,
