CSS list properties: list-style-type and list-style-position

CSS list properties: list-style-type and list-style-position, specific code examples are required

In front-end development, we often need to use lists for display information. CSS provides some properties to beautify and customize the style of lists. The two most commonly used properties are list-style-type and list-style-position.

1. list-style-type attribute
   list-style-type attribute is used to define the type of markup symbol for list items. By default, the browser will automatically generate mark symbols based on the order of the list, usually a solid dot (disc). But we can change the style of the markup symbol through the list-style-type attribute.

The following are some commonly used list-style-type values ​​​​and their effects:

• disc: solid dots
• circle: hollow circle Point
• square: solid square
• none: no marking symbol
• decimal: decimal number (1, 2, 3, ...)
• decimal -leading-zero: decimal numbers with leading zeros (01, 02, 03, ...)
• lower-roman: lowercase Roman numerals (i, ii, iii, ...)
• upper-roman: uppercase Roman numerals (I, II, III, ...)
• lower-alpha: lowercase letters (a, b, c, ...)
• upper-alpha: uppercase letters (A, B, C, ...)

For example, if we want to change the marker symbol of the list to a solid square, we can use the following code:

ul {
  list-style-type: square;
}

2. list-style-position attribute
   The list-style-position attribute is used to define the position of the list item mark symbol. By default, the marker symbol is placed to the left of the list item. We can use the list-style-position property to place the marker symbol outside or inside the list item.

The following are the two values ​​​​of list-style-position and their effects:

• inside: The mark symbol is located inside the list item
• outside: The marker symbol is placed outside the list item

For example, if we want to place the marker symbol of the list item outside, we can use the following code:

ul {
  list-style-position: outside;
}

3. Comprehensive example
   Here is an example that combines list-style-type and list-style-position to show an ordered list of custom styles:

ol {
  list-style-type: decimal;
  list-style-position: inside;
  padding-left: 20px;
}

ol li {
  padding-left: 10px;
  line-height: 1.5;
}

In this example, the list markup symbol It is a decimal number, placed inside the list item, and adds a certain left margin and line height to the list item.

Summary
By using the list-style-type and list-style-position attributes, we can customize the style of the list to make it more consistent with our design needs. The above examples are just some of the common usages. In fact, there are some other values ​​for these two properties to choose from. By flexibly using these attributes, we can create more diverse list effects.
