I'm having a similar problem, I'm trying to create a site with a dynamic header and video underneath.  I've selected dynamic header but it stays white. Were you able to figure this one out?

Just wanted to update this post - Squarespace rolled out an update and you no longer need a code solution here. In the auto layout (list) section, just go to Edit Content > Design > Size & Space. Scroll to the bottom and there is now the option to make each item the same height under Position:

not going to do much by asking Squarespace here on the forums for a feature that is crucial/essential to running a business. you need to log in a ticket and make the request there so they see it. they have mentioned before they do not really monitor the forums for feature requests.

If Squarespace allows the manual creation of gift cards, it might be possible -- and you'd have to create the free gift card manually. As it is, as store owner, you can't even use gift cards as a promotional tool because you'd have to buy the gift cards from yourself  -- the "solution" I was given back in May when I asked why I can't create gift cards to give away (which, IMO, was a ridiculous solution).

Not sure if this will work, but some code I had from one of my sites. 
Assuming they are image blocks you wan't to reduce - Note, you may need to alter other things this just makes them smaller on the page.
 
/* Resize footer images */
  footer .sqs-image .sqs-image-content img, footer .image-block {

    transform: scale(0.5)
 

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.
