Make all your icons the same width so they can easily vertically align, like in a list or navigation menu.
Add a class of fa-fw on the HTML element referencing your icon to set one or more icons to the same fixed width. This is great to use when varying icon widths (e.g. a tall but skinny icon atop a wide but short icon) would throw off vertical alignment. For clarity in the following example, we’ve added a background color on the icon so you can see the fixed width and also bumped up the font-size of the parent element.
<div style="font-size: 2rem;">
<div><i class="fa-solid fa-skating fa-fw" style="background:DodgerBlue"></i> Skating</div>
<div><i class="fa-solid fa-skiing fa-fw" style="background:SkyBlue"></i> Skiing</div>
<div><i class="fa-solid fa-skiing-nordic fa-fw" style="background:DodgerBlue"></i> Nordic Skiing</div>
<div><i class="fa-solid fa-snowboarding fa-fw" style="background:SkyBlue"></i> Snowboarding</div>
<div><i class="fa-solid fa-snowplow fa-fw" style="background:DodgerBlue"></i> Snowplow</div>
</div>
