Limit the allowed nesting depth.
限制允许嵌套的深度。
a { & > b { top: 0; }
/** ↑
* This nesting */
This rule works by checking rules' and at-rules' actual "nesting depth" against your specified max. Here's how nesting depths works:
该规则检查规则和 at 规则的实际嵌套深度与你指定的最大值。以下展示嵌套深度是如何工作的:
a {
& b { /* nesting depth 1 */
& .foo { /* nesting depth 2 */
@media print { /* nesting depth 3 */
& .baz { /* nesting depth 4 */
color: pink;
}
}
}
}
}
Note that root-level at-rules will not be included in the nesting depth calculation, because most users would take for granted that root-level at-rules are "free" (because necessary). So both of the following .foo
rules have a nesting depth of 2, and will therefore pass if your max
is more than or equal to 2:
注意,根级别的 at 规则将 不会被算进嵌套深度里,因为大多数用户会理所当然地认为根级别的 at 规则是必须的。因此,下面的 .foo
规则嵌套深度都为 2
,如果你的 max
大于等于 2,将通过规则。
注意,根级别的 at 规则将 不会被算进嵌套深度里,因为大多数用户会理所当然地认为根级别的 at 规则是必须的。因此,下面的 .foo
规则嵌套深度都为 2
,如果你的 max
小于等于 2,将通过规则。
a {
b { /* 1 */
.foo {} /* 2 */
}
}
@media print { /* ignored */
a {
b { /* 1 */
.foo {} /* 2 */
}
}
}
This rule integrates into stylelint's core the functionality of the (now deprecated) plugin stylelint-statement-max-nesting-depth
.
该规则已整合到 stylelint 的核心功能插件(现在已废弃)stylelint-statement-max-nesting-depth
。
int
: Maximum nesting depth allowed.
int
:所允许的最大嵌套深度。
For example, with 2
:
例如,最大嵌套深度为 2
:
The following patterns are considered warnings:
以下模式被认为是个警告:
a {
& .foo { /* 1 */
&__foo { /* 2 */
& > .bar {} /* 3 */
}
}
}
a {
@media print { /* 1 */
& .foo { /* 2 */
& .bar {} /* 3 */
}
}
}
The following patterns are not considered warnings:
以下模式正常:
a {
& .foo { /* 1 */
&__foo {} /* 2 */
}
}
a .foo__foo .bar .baz {}
@media print {
a {
& .foo { /* 1 */
&__foo {} /* 2 */
}
}
}
ignore: ["at-rules-without-declaration-blocks"]
Ignore at-rules that only wrap other rules, and do not themselves have declaration blocks.
忽略只包裹了其他规则,而且没有自己的声明块的 at 规则,
For example, with 1
:
例如,最大嵌套深度为 1
:
The following patterns are considered warnings:
以下模式被认为是个警告:
As the at-rules have a declarations blocks.
因为 at 规则有一个声明块。
a {
&:hover { /* 1 */
@media (min-width: 500px) { color: pink; } /* 2 */
}
}
a {
@nest > b { /* 1 */
.foo { color: pink; } /* 2 */
}
}
The following patterns are not considered warnings:
以下模式正常:
As all of the following .foo
rules would have a nesting depth of just 1.
因为下面所有的 .foo
规则嵌套深度为 1。
a {
.foo { color: pink; } /* 1 */
}
@media print { /* ignored regardless of options */
a {
.foo { color: pink; } /* 1 */
}
}
a {
@media print { /* ignored because it's an at-rule without a declaration block of its own */
.foo { color: pink; } /* 1 */
}
}
ignoreAtRules: ["/regex/", "string"]
Ignore the specified at-rules.
忽略指定的 at 规则。
For example, with 1
and given:
例如,最大嵌套深度为 1
,给出:
["/^my-/", "media"]
The following patterns are considered warnings:
以下模式被认为是个警告:
a {
@import print { /* 1 */
b { top: 0; } /* 2 */
}
}
a {
@not-my-at-rule print { /* 1 */
b { top: 0; } /* 2 */
}
}
The following patterns are not considered warnings:
以下模式正常:
a {
@media print { /* 1 */
b { /* 2 */
c { top: 0; } /* 3 */
}
}
}
a {
b { /* 1 */
@media print { /* 2 */
c { top: 0; } /* 3 */
}
}
}
a {
@my-at-rule print { /* 1 */
b { /* 2 */
c { top: 0; } /* 3 */
}
}
}
a {
@my-other-at-rule print { /* 1 */
b { /* 2 */
c { top: 0; } /* 3 */
}
}
