覆盖Rails SASS引导CSS

Question

我正在使用Rails 4.1.8，sass-rails 4.0.3和bootstrap-sass 3.3.3，我很难覆盖一些CSS。

我的application.css.sass文件看起来像这样

/*
 * This is a manifest file that'll be compiled into application.css, which will include all the files
 * listed below.
 *
 * Any CSS and SCSS file within this directory, lib/assets/stylesheets, vendor/assets/stylesheets,
 * or vendor/assets/stylesheets of plugins, if any, can be referenced here using a relative path.
 *
 * You're free to add application-wide styles to this file and they'll appear at the bottom of the
 * compiled file so the styles you add here take precedence over styles defined in any styles
 * defined in the other CSS/SCSS files in this directory. It is generally better to create a new
 * file per style scope.
 *
 *= require_tree .
 *= require_self
 */


@import "bootstrap-sprockets"
@import "bootstrap"

我还有一个名为header.css.scss的文件，我试图给header标签设置字体大小，并且它不会改变。 但是，我测试时其他3个属性正确更改。

header{
  background: #0099da;
  color: #ffffff;
  font-size: 2em;
  height:100px;
}

当我尝试更改图例标签时，也会发生相同的情况。

Answer 1

您需要在 bootstrap 之后导入header.css.scss 。

Answer 2

假装header.css.scss与application.css.scss放在同一文件夹中，它应类似于：

/*
 * (…)
 *
 *= require_self
 *= require_tree .
 */

@import "bootstrap-sprockets"
@import "bootstrap"

我只是简单地更改了Sprockets需求顺序。

但是，我强烈建议您专门导入文件，以避免由于错误的导入顺序而导致的优先噩梦。

/*
 * (…)
 *
 *= require_self
 *= require header.css.scss
 */

@import "bootstrap-sprockets"
@import "bootstrap"
