Squarespace released an Accordion Block a few weeks ago.
Here are some useful tips/code when you use the accordion block
Change Dividers Color
/* accordion divider color */
.accordion-divider {
color: #ff00ff !important;
}
Change Arrows Color
/* accordion arrows color */
.accordion-block .arrow {
border-color: #ffff00 !important;
}
Add icons before Accordion Titles
this example code for 3 accordion titles [nth-child(1), nth-child(2), nth-child(3)]
/* Accordion icons before titles */
li.accordion-item .accordion-item__title:before {
content: "";
width: 20px;
height: 20px;
display: inline-block;
background-repeat: no-repeat;
background-size: contain;
background-position: bottom center;
}
li.accordion-item:nth-child(1) .accordion-item__title:before {
background-image: url(https://cdn.pixabay.com/photo/2021/11/02/15/30/tealights-6763542__340.jpg);
}
li.accordion-item:nth-child(2) .accordion-item__title:before {
background-image: url(https://cdn.pixabay.com/photo/2019/10/23/06/30/hamburg-4570577__340.jpg);
}
li.accordion-item:nth-child(3) .accordion-item__title:before {
background-image: url(https://cdn.pixabay.com/photo/2021/02/17/08/02/woman-6023442__340.jpg);
}
Accordion Inside Accordion
You can use Accordion Tabs Plugin + Accordion Block to achieve this.
Different Color for Accordion Titles
/* accordion title colors */
li.accordion-item:nth-child(1) .accordion-item__title {
color: red;
}
li.accordion-item:nth-child(2) .accordion-item__title {
color: blue;
}
li.accordion-item:nth-child(3) .accordion-item__title {
color: violet;
}
Change a specific word color in Accordion Content
To make specific word different color, first make it bold then use this CSS
/* accordion content specific word color */
.accordion-item__description strong {
font-weight: normal;
color: red;
}
Accordion Title Background Color
/* accordion title background */
.sqs-block-accordion .accordion-item__title-wrapper {
background-color: #32a4e6;
}
Accordion Content Background
/* accordion content background */
.sqs-block-accordion .accordion-item__dropdown--open {
background-color: #262853;
color: white;
}
Add Unordered List in Accordion Content
First, add some text then Underline them

Next, use this CSS
/* Accordion Content - Add Unordered list */
span[style*="text-decoration"]:before {
content: "";
display: inline-block;
width: 3px;
height: 3px;
background-color: black;
vertical-align: middle;
margin-right: 3px;
}
span[style*="text-decoration"] {
text-decoration: none !important;
}
