Problem solved as going to previous css found i had previously reduced the block summary width to 80%. Removing that means everything is lined up. 

The situation is unchanged on both Squarespace 7.0 and 7.1 - digital products cannot have variants. See this older thread, although I suspect this is what you followed:
 

Hi Brandon, thanks for the offer. In the end I decided not to include captions and keep it clean so i am ok now.

@IvanOB: I'll take a look and see if things can be tweaked easily. If you can provide a link to an example page, it might speed things up.
@SW_2020: This might be doable. If you can provide a link to a page that shows the issue, that'd be great. Otherwise, I'll do what I can to recreate it in my own demo (but that might not be easy). Also, what gallery style are you using?
 

There is a min-height of 33vh set on sections. You need to override that to get the sections smaller. 

For all sections this would be:
.page-section { min-height: 0 !important; } For a specific section you need to specify the data-section-id that can be found by inspecting the page code using your browser's developer tools.

Somethig like this:
.page-section[data-section-id="5d979fd8590a832f3c411579"] { min-height: 0 !important; }

Some custom code (CSS) to change color

Notes
Add code to Home > Design > Custom CSS The code is based on demo at squarespace.com/templates, so they may not work for some websites or navigation with dropdown If the code doesn't work, try adding !important to after, eg: color: #f1f2f3 !important; If you have any questions/found issues, just comment below or send me a private message.

Update 5/26/2020: Squarespace has added the ability to add image descriptions/captions to 7.1 gallery sections. See here. There are some limitations, such as not appearing in lightbox view and not supporting multiple lines. So, the workaround below may still be of use.
---------------------------------------------------------------------
Hi @dan3.
Looking at the underlying gallery code, it appears that image descriptions are in-the-works to one degree or another. In the mean time, I've created a bit of code you can use to add image descriptions/captions to gallery sections in Squarespace 7.1 .
View Demo Site
JavaScript
Insert via sitewide footer code injection. If you only want to add descriptions to some (not all) galleries, pass your own CSS selector into addGalleryItemDescriptions() (for example: "section[data-section-id='5db1f73f7a30760db464bb02']") For images within a targeted gallery that you do not want a description to appear, you must enter a space as the description (otherwise the filename will show). <script> /** * Add descriptions/captions to galleries in Squarespace 7.1. * JavaScript * © @brandon (Squarespace Forum User) * This software is provided "as is", without warranty of any kind, express or implied. */ document.addEventListener("DOMContentLoaded", function() { addGalleryItemDescriptions(); function addGalleryItemDescriptions(gs, gdzs) { var a=['querySelectorAll','section.gallery-section,\x20.gallery-lightbox','length','[class*=\x27-item\x27]:not([class*=\x27item-\x27])','getElementsByTagName','img','alt','trim','createElement','div','className','gallery-item-description','textContent','appendChild'];var b=function(c,d){c=c-0x0;var e=a[c];return e;};(function(c,d){var e,f,g,h,i,j,k;e=document[b('0x0')](c?c:b('0x1'));i=e[b('0x2')];while(i--){f=e[i][b('0x0')](d?d:b('0x3'));j=f[b('0x2')];while(j--){g=f[j][b('0x4')](b('0x5'))[0x0][b('0x6')][b('0x7')]();if(g){h=document[b('0x8')](b('0x9'));h[b('0xa')]=b('0xb');h[b('0xc')]=g;f[j][b('0xd')](h);}}}}(gs,gdzs)); } }); </script>  
CSS
Insert in "Customer CSS", via the CSS Editor. The CSS below is very basic, adding a white box around the description and generally placing it at the bottom. You can customize to your heart's content. /** * Add descriptions/captions to galleries in Squarespace 7.1. * CSS * © @brandon (Squarespace Forum User) * This software is provided "as is", without warranty of any kind, express or implied. */ body { width: 100%; } section.gallery-section [class*='-item']:not([class*='-item-']):not([class*='-reel']):not([class*='-slideshow']) { position: relative; } .gallery-item-description { font-family: "Roboto", sans-serif; font-size: 16px; color: black; } .gallery-grid, .gallery-strips, .gallery-masonry, .gallery-reel, .gallery-fullscreen-slideshow { .gallery-item-description { position: absolute; width: 100%; bottom: 0; background-color: rgba(255, 255, 255, 0.7); padding: 2% 6%; box-sizing: border-box; } } .gallery-slideshow, .gallery-fullscreen-slideshow, .gallery-reel { .gallery-item-description { padding: 10px 25px; opacity: 1; transition: opacity 0.2s; } .gallery-slideshow-item:not([data-in="true"]), .gallery-fullscreen-slideshow-item:not([data-in="true"]), figure[style*="-9999"] { .gallery-item-description { opacity: 0; } } } .gallery-slideshow { .gallery-slideshow-list { position: static; } .gallery-slideshow-item-wrapper, .gallery-item-description { flex: 1 1 auto; } } .gallery-reel { .gallery-item-description { text-align: center; left: 50%; transform: translateX(-50%); } &[data-width="inset"], &[data-width="inset"] { .gallery-item-description { max-width: 88vw; } } &[data-width="full-bleed"] { .gallery-item-description { max-width: 100vw; } } } .gallery-lightbox .gallery-item-description { margin-top: 1em; padding: 1em 2em; background-color: rgba(225, 225, 225, 1); transition: opacity 0.1s ease-out; } .gallery-lightbox-item[data-in=false] .gallery-item-description { opacity: 0; } This is of course experimental. Do let me know how it works for you, or if you have questions.
If you reply to this post, please do not quote the code in your reply. Doing so will create copies of the code which A) I would prefer not be copied and B) will propagate old versions of the code which are likely to fall out of date.
