html中这两个按纽总是对不齐!代码如下

<div class="formBar">
                                        <ul>
                                            <li>
                                                <div class="buttonActive">
                                                    <div class="buttonContent">
                                                        <button type="submit">
                                                            保存
                                                        </button>
                                                    </div>
                                                </div>
                                            </li>
                                            <!-- <li>
                                            <div class="button"><div class="buttonContent"><button type="button" class="close">取消</button></div></div>
                                            </li> -->
                                            <li>
                                                <!-- <div class="button"> -->
                                                <div class="buttonActive">
                                                    <div class="buttonContent">
                                                  <a href="<%=basePath %>admin/person/index.html" target="navTab" rel="person">返回</a>
                                                    </div>
                                                </div>
                                            </li>
                                        </ul>
                                    </div>
