removing hover effect on specific pages

Hello @sacconi,

Please include the theme name.

it’s a custom theme from Underscores

Add this to Additional CSS:

.page-id-14087 .wp-block-image:hover {
    border-color: lightgray;
    background-color: transparent;
}

There is a similar rule that accomplishes the orange hover effect, this rule must occur anywhere after that one. To do similarly for other pages, determine what the page’s ID is and use it in place of the 14087 used here.
