css - 将 CSS 转换为 LESS 选择器

Question

我有这样的 CSS:

.button-navigation-container button {
   /*some properties*/
}

        .button-navigation-container button.back-button,
        .button-navigation-container button.cancel-button {
            text-align: right;
            padding-right: 2%;
        }

但现在我想转换为 LESS，但我不确定应该使用哪种选择器来获取 back-button 和 cancel-button相同的风格。像这样:

.button-navigation-container button {
       /*some properties*/

            /*Selector for cancel-button and back-button ?*/{
                text-align: right;
                padding-right: 2%;
            }
}

我应该使用 extend() 吗？ ？

Answer 1

少

.button-navigation-container {
    button {
        /*some properties for button*/
        &.back-button, &.cancel-button {
            text-align: right;
            padding-right: 2%;
        }
    }
}

样式表(由LESS生成)

.button-navigation-container button {
  /*some properties for button*/

}
.button-navigation-container button.back-button,
.button-navigation-container button.cancel-button {
  text-align: right;
  padding-right: 2%;
}
