TLDR

To resize your list marker images, don't use list-style-image, instead, apply CSS background properties. Set the image size using background-size and tweak the padding for perfect alignment.

Example:

li.custom-marker { list-style: none; /* Bulletproof way to kill bullets */ background: url('icon.svg') no-repeat; /* Back with a background */ background-size: 16px 16px; /* Resize it before your eyes */ padding-left: 24px; /* Space, the final frontier */ }

The solution resides in:

  • background-size property to dictate the image dimensions
  • padding-left property to nudge the image into place

Image Scaling and Positioning

SVG Scaling Techniques

SVGs offer resolution independence perfect for sharp visuals at any size. To scale SVG images in the list:

li::before { content: ''; display: inline-block; width: 20px; /* I am the size captain now */ height: 20px; background: url('icon.svg') no-repeat; background-size: contain; /* Fit or bust */ }

A trick to remember: use the viewBox attribute of SVG for responsive scaling and refrain from resizing SVG files directly to maintain the crisp quality of the images.

Controlling SVG Icon Positioning

To exert more control on positioning, utilize background-position and a sprinkle of negative margins:

li::before { margin-right: -25px; /* Pushing limits, or just images */ }

A flexible solution like this adds more control over the image's spacing relative to the list text, giving your lists that tailor-made look.

Creating Style-savvy Lists

Dropping list-style-image for Flexibility

If you want more dominion over image size and quality, use <img /> tags instead of list-style-image. This offers more control:

<li><img src="icon.svg" class="list-image" />List item</li>

Then apply CSS styling:

.list-image { width: 20px; /* Instead of a cookie cutter approach */ height: 20px; }

Consistency Across Devices

To fend off cross-device inconsistencies, choose pure CSS for list icons:

li::before { content: ''; /* Can't start a fire without a spark */ display: inline-block; /* Squaring up for inline duty */ /* Additional styling */ }

This ensures smooth rendering across different devices and browsers.

Multiple SVG icons

Include different SVG icons in a single list for variety:

ul li:first-child::before { background-image: url('first-icon.svg'); /* A first impression matters */ }

Play around with margin and padding to fine-tune icon placement:

ul li { margin-bottom: 5px; /* One small step for CSS */ }
