我正在使用gulp.spritesmith来自动化精灵图像和css生成.一切都很好,除了生成的css是haivng"icon-"前缀.我不想添加此前缀,因为我有现有的HTML标记,我不想更改标记.以下是我的gulp任务.

'use strict';
var gulp = require('gulp');
var spritesmith = require('gulp.spritesmith');


gulp.task('sprite', function () {    

    var spriteData =
            gulp.src('./sprite/*.*') // source path of the sprite images
            .pipe(spritesmith({
                imgName: 'sprite.png',
                cssName: 'sprite.css'
            }));

    spriteData.img.pipe(gulp.dest("./css")); // output path for the sprite
    spriteData.css.pipe(gulp.dest("./css")); // output path for the CSS
});

以下是我生成的CSS.

.icon-icon1 {
  background-image: url(sprite.png);
  background-position: 0px 0px;
  width: 120px;
  height: 120px;
}
.icon-icon2 {
  background-image: url(sprite.png);
  background-position: -120px 0px;
  width: 120px;
  height: 120px;
}

请帮助压制"icon-".
