I am trying to create a design from a graphic artists and i have successfully created the button that acts like a checkbox, however i cant seem to figure out the CSS to mimic the design. Its grey but on hover/click(checked) it changes color. I'm using bootstrap and fontawesome to try and achieve this.
IMG of functionality im trying to replicate:

#canvasBranch-ck-button {
margin: 4px;
background-color: #fff;
border-radius: 4px;
border: 1px solid #D0D0D0;
overflow: auto;
float: left;
width: 150px;
}
#canvasBranch-ck-button:hover {
background: #fff;
color: #ff4c00;
border-color: #ff4c00;
cursor: pointer;
}
#canvasBranch-ck-button label {
float: left;
width: 100%;
}
#canvasBranch-ck-button label span {
text-align: center;
padding: 3px 0px;
display: block;
}
#canvasBranch-ck-button label span.iconSpan {
background-color: #D0D0D0;
color: #fff;
}
#canvasBranch-ck-button label input {
position: absolute;
top: -20px;
}
#canvasBranch-ck-button input:checked+span.textSpan {
color: #ff4c00 !important;
}
#canvasBranch-ck-button input:checked+span.iconSpan {
background-color: #ff4c00;
}
<div id="canvasBranch-ck-button">
<label class="d-flex mb-0">
<input type="checkbox" value="canvasBranch">
<span class="flex-fill align-items-center iconSpan"><i class="fas fa-angle-left"></i></span>
<span class="align-items-center flex-fill textSpan">Canvas Branch</span>
</label>
</div>
+is the "adjacent sibling combinator", meaning it only applies if the given items are directly beside eachother. Your checkbox andtextSpanare not adjacent siblings, therefore this will not work:input:checked + span.textSpan. You'll want to use the regular sibling combinator instead:input:checked ~ span.textSpan<div>based on the checkbox. They would have to be siblings instead. You may have to re-think your HTML.
