Change background in new page

Hello,
I am hopeless…I created in Illdy new pages, but I dont know, how to change a background picture. I have already found this is it:

<header id=“header” class=“header-blog header-has-sticky-menu” style=“background-image: url(https://zadavacka.cz/wp-content/themes/illdy/layout/images/blog/blog-header.png);background-attachment: fixed;”>

I tried to change it in custom CSS according instruction I found here in forum, but I didnt success.

My web page is: https://zadavacka.cz
I tried to change it on page: https://zadavacka.cz/registrace/

Thank you very much for your instruction!!!

Hi,

Thanks for contacting us.

I am a bit confused here, do you want to change the background image for the entire page or the header/jumbotron?

Take care.

I need to change picture of cappuccino only on this page: https://zadavacka.cz/registrace/
(there is a cup of cappuccino with cinamon)

here is a background picture I want to change

I have tried this, but then there is no background picture:
.page-id-26 #header {
background-image: url(“https://zadavacka.cz/wp-content/uploads/2018/07/black-and-white-blur-gray-34088-1.jpg”) !important;
}

Hello there,

That codes seems correct. Please check the page id to ensure it is the right page id.

Best Regards,

Page ID is correct, as you can see on the screen picture I attached.

I thought there could be a problem with image size, so I found the picture with same size as this one:
https://zadavacka.cz/wp-content/themes/illdy/layout/images/blog/blog-header.png

but it still doesnt work :frowning:
background is white, when I insert that code…because when I scroll down on the page I can see green sticky menu (up).

Hi there,
Thanks for writing back.
In that case, could you kindly provide us with temporary admin access to your WordPress Dashboard so that we can have a closer look into this.

You may create a new administrator user within your WordPress Dashboard using your email address. You may then copy the login credentials to us in your reply.

I look forward to your reply.

Hi,
problem is solved ? !! After two days of studying CSS I found it in user environment: dashboard - custom - blog options - blog archive header image.
But thank you for your help.
