hi, im having an issue with the 'store' button on my homepage. it has turned white for some reason and i cant get it to be dark grey like the other buttons that are on my 'about' page. i've checked the colour palette and there is nothing white selected so i'm not sure how to change it

You can add this to Design > Custom CSS

/* Home store button */
body.homepage .sqs-block-button-element[href="/store"] {
    color: darkgrey;
}

this only changed the font colour,  i'd like the button even the frame to be the grey then when you hover it inverts like on the /about page with the delivery and return button. this is the colour code i found in the inspect element

.primary-button-style-outline .black .sqs-block-button-element--small, .primary-button-style-outline .black .sqs-block-button-element--medium, .primary-button-style-outline .black .sqs-block-button-element--large, .primary-button-style-outline .black .header-actions .btn {
    color: #434446;
    border-color: #434446;
    background: transparent;
}
