Mobile-Only Edits: Overriding Text Alignment for 1 Block

Site URL: https://chameleon-cobalt-rwzt.squarespace.com/

Hi all,

I am trying to optimize a site I am working on for mobile but encountering a lot of challenge. (Side note, it seems like Squarespace needs to expand their mobile/tablet only customizations a lot? Other site-building platforms I've used have had much more built in flexibility. 

I am trying to figure out how to override the text and button alignment only within one block on the homepage. I'm not quite sure what I'm doing wrong... nothing seems to affect the text. Does anyone have any tips? 

@media screen only and (max-width: 640px) {
  #block-a655a39c1604a6f3cee0 {
    text-align: center !important ;
    align: center !important;
    .button-block>div {
		text-align: center !important;
    }
  }
}

You mean center Welcome to the garden text + button on mobile?

Add to Design > Custom CSS

/* Mobile Welcome to the garden text */
@media screen and (max-width:767px) {
div#block-a655a39c1604a6f3cee0 * {
    text-align: center !important;
}
div#block-242a33d4975bff65945c div {
    text-align: center;
}
}
