覆蓋Rails SASS引導CSS

Question

我正在使用Rails 4.1.8，sass-rails 4.0.3和bootstrap-sass 3.3.3，我很難覆蓋一些CSS。

我的application.css.sass文件看起來像這樣

/*
 * 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"

我還有一個名為header.css.scss的文件，我試圖給header標簽設置字體大小，並且它不會改變。 但是，我測試時其他3個屬性正確更改。

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

當我嘗試更改圖例標簽時，也會發生相同的情況。

Answer 1

您需要在 bootstrap 之后導入header.css.scss 。

Answer 2

假裝header.css.scss與application.css.scss放在同一文件夾中，它應類似於：

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

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

我只是簡單地更改了Sprockets需求順序。

但是，我強烈建議您專門導入文件，以避免由於錯誤的導入順序而導致的優先噩夢。

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

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