如何在HTML中显示一个由单元格表中的一种颜色填充的圆圈？

我需要在表格单元格中显示由一种颜色填充的圆圈.不知何故,我找到了一个有效但无法可靠运行的例子.请看下面的代码.
在IE上,圆圈变成垂直拉长的椭圆形.在具有更大细胞高度的Mozilla上也会发生同样的情况.

<!DOCTYPE HTML>
<html>
    <head>
        <title>circle</title>
        <style type="text/css">
            .circle_green { 
                width:1%;
                padding:10px 11px;
                margin:0 auto;
                border:2px solid #a1a1a1;
                border-radius:25px;
                background-color:green;
            }
        </style>
    </head>
    <body>
        <table border="1">
            <tr>
                <td>
                    <div class="circle_green"></div>
                </td>
            </tr>
        </table>
    </body>
</html>

更改Spring MVC应用程序的jar集导致java.lang.NoSuchMethodError错误

我有工作的Spring WEB MVC应用程序.我需要添加Hibernate持久层,所以我从Github下载了Spring Pet Clinic应用程序:http: //spring.io/blog/2013/03/21/spring-petclinic-is-on-github

仅从Petclinic应用程序(Spring版本4.0.1)将jar更改为jar集导致以下错误

在Angular 2中,router-outlet'不是已知元素

我在Stack Overflow中看到了类似的关于'router-outlet'的问题,但响应对我没有帮助.

这些是我的模块,他们不会在Webclipse中给出任何错误

nav.component.ts

import { RoutingModule } from '../routing/routing.module';
import { Component, OnInit } from '@angular/core';
import {NgModule} from '@angular/core';

@Component({
selector: 'app-nav',
templateUrl: './nav.component.html',
styleUrls: ['./nav.component.css']
})

@NgModule ({
imports: [
    RoutingModule,
]
})
export class NavComponent implements OnInit {
constructor() { }
ngOnInit() {
}
}
