Lists

These properties define the appearance of lists (<ul>, <ol>, <li>) as well as definition lists (<dl>, <dt>, <dd>).
They mainly control bullets (or numbers), their position, their type, and the option to replace them with an image.

list-style	Shorthand property combining list-style-type, list-style-position, and list-style-image. Can also remove bullets with none.
list-style-type	Defines the type of bullet or numbering (e.g., disc, circle, square, decimal, lower-roman, none).
list-style-position	Defines whether the bullet is displayed inside (inside) or outside (outside) the content block.
list-style-image	Defines an image as a custom bullet (url(...)).

Simple example

ul.custom {
  list-style-type: square;          /* Square bullets */
  list-style-position: inside;      /* Bullets inside the text */
}

ol.roman {
  list-style-type: upper-roman;     /* Roman numeral numbering */
}

ul.image {
  list-style-image: url("bullet.png"); /* Image as a custom bullet */
}

ul.none {
  list-style: none;                 /* Removes bullets */
}

Key takeaways

• list-style lets you configure bullet type, position, and image in a single line.
• list-style-type is the most commonly used to change the shape or remove bullets.
• list-style-image allows graphic customization but is rarely used (prefer ::marker or ::before).
• marker-offset is deprecated and replaced by list-style-position or the ::marker pseudo-element.
