susy 2.0 在断点处更改列 [英] susy 2.0 change columns at breakpoint

问题描述

1. 我没有使用指南针
2. 我更喜欢使用 Breakpoint.scss
3. 我在使用 susy 2.0

我知道有很多关于这个问题的帖子，但我有 0 次运气找到关于这个主题的 Breakpoint.scss 和 Susy 2.0.

I know there are lot of posts with this question but I'm having 0 luck finding any regarding Breakpoint.scss and Susy 2.0 on this topic.

@import "susy";
@import "breakpoint";

$medium: 800px;

$susy: (
  columns: 6,
  gutters: 3/4,
  gutter-position: split
);

@include breakpoint($medium) {
  $susy: layout(12 1/4 split);
}

body {
  @include container(show);

  @include breakpoint($medium) {
    @include container(show);
  }
}

我是否必须使用 susy-breakpoint 或者可以实现这样的目标?我想要 6 列在/低于 800 像素和 12 列在/高于 800 像素

Do I have to use susy-breakpoint or can something like this be achieved? I want 6 columns at anything at/below 800px and 12 at/above 800px

我试图保持 DRY，所以在我的样式中添加一个 susy-breakpoint 无济于事.

I'm trying to stay DRY so adding a susy-breakpoint in my styles does not help.

我也试过下面的代码，但我想我只是在某处出错，导致它无法正常工作.

I've also tried below code but I think I just have an error somewhere cause it's not working.

$susy: layout(6 1/4 split);

$small: 400px, 6 1/4 split;
$medium: 800px, 8 1/4 split;
$large: 1000px, 12 1/4 split;

@mixin media($size) {
  @include susy-breakpoint($size...) {
    @content;
  }
}

body {
  @include container(show);

  @include media($small) {
    @include container(show);
  }

  // debugging. didnt work either
  @include susy-breakpoint($small...) {
    @include container(show);
  }
}

推荐答案

我不知道你的 media mixin 是做什么的，所以我无法真正评论与此相关的任何内容.您最初的示例不起作用，因为 Sass、CSS 和 Susy 不知道 DOM - 或媒体查询之间的关系.当您在一个媒体查询中更改 $susy 的值时，这不会传播到所有类似的媒体查询上下文.因此，每次您想要断点更改布局上下文时，您都必须同时设置媒体查询和所需的布局.

I don't know what your media mixin does, so I can't really comment on anything related to that. Your initial example doesn't work because Sass, CSS, and therefor Susy, are not aware of the DOM - or relationships between media-queries. When you change the value of $susy inside one media-query, that does not propagate to all similar media-query contexts. Because of that, you do have to set both the media-query and the desired layout every time you want a breakpoint to change the layout context.

susy-breakpoint 不是唯一的方法，但它是最短的.这是简写​​:

susy-breakpoint is not the only way to do that, but it is the shortest. Here's the longhand:

body {
  @include container(show);

  @include breakpoint(800px) {
    @include with-layout(8) { // default is set to 8-columns
      @include container(show);
    } // default is returned to global setting
  }
}

您的 $small 断点当前不会改变任何东西，因为它与您的默认布局相同.较大的将更改嵌套代码的布局上下文——尽管您可以简化:由于1/4 拆分"装订线根本没有变化，因此不需要在每个断点处重新声明它们.

Your $small breakpoint currently doesn't change anything, because it is identical to your default layout. The larger ones will change the layout context for nested code — though you can simplify: Since `1/4 split' gutters aren't changing at all, they don't need to be re-stated at every breakpoint.

$susy: layout(6 1/4 split);
$medium: 800px, 8;

body {
  @include container(show);

  @include susy-breakpoint($medium...) {
    @include container(show);
  }
}

这将与上面的简写相同.

That will be identical to the longhand above.
