我正在使用Magento 2。我想在扩展块中设置颜色和其他较少的变量，例如:@primary__color .

有人知道怎么做吗?

我通过使用admin颜色配置从phtml模板文件生成自定义css文件来实现。

protected function generateStoreCss($type, $storeId) {
        $store = $this->_storeManager->getStore($storeId);
        if(!$store->isActive())
            return;
        $storeCode = $store->getCode();
        $str1 = '_'.$storeCode;
        $str2 = $type.$str1.'.css';
        $str3 = $this->_cssconfigData->getCssConfigDir().$str2;
        $str4 = 'mypath/css/'.$type.'.phtml';
        $this->_coreRegistry->register('cssgen_store', $storeCode);
        try {
            $block = $this->_layoutManager->createBlock('Vendor'Module'Block'Template')->setData('area','frontend')->setTemplate($str4)->toHtml();
            if(!file_exists($this->_cssconfigData->getCssConfigDir())) {
                @mkdir($this->_cssconfigData->getCssConfigDir(), 0777);
            }
            $file = @fopen($str3,"w+");
            @flock($file, LOCK_EX);
            @fwrite($file,$block);
            @flock($file, LOCK_UN);
            @fclose($file);
            if(empty($block)) {
                throw new 'Exception( __("Template file is empty or doesn't exist: ".$str4) );
            }
        } catch ('Exception $e) {
            $this->_messageManager->addError(__('Failed generating CSS file: '.$str2.' in '.$this->_cssconfigData->getCssConfigDir()).'<br/>Message: '.$e->getMessage());
        }
        $this->_coreRegistry->unregister('cssgen_store');
    }

然后导入css文件到布局中
