For Hristina: Single Page Background Change

Hi Hristina, you had helped me with changing a single page’s background last week. You sent me the following CSS to insert:

.page-id-XXX #main-content {
background-image: url (‘URL TO YOUR IMAGE’);
background-repeat: no-repeat;
background-size: cover;
}

I did this, but it did not change. Please the code I entered with the page ID and url for the image.

.page-id-1442 #main-content {
background-image:(‘http://alphaenergyalliance.com/wp-content/uploads/2015/05/Louvre_Pyramid_icon_2Light_70.png’);
background-repeat: no-repeat;
background-size: cover; }

Please let me know if I did something wrong.

Thank you,
Melita
