bootstrap - 如何在响应式图像上定位文本

时间:2015-10-08 15:05:51

标签: jquery html css twitter-bootstrap

我正在尝试这种布局

enter image description here

我已将此代码用于背景图片

<div class="container-fluid" style="padding: 0px;">
        <img class="img-responsive center-block header1" src="images/header.jpg" />
</div>

之后,我不知道如何使用引导程序将徽标或导航栏放在背景图像上,如上图所示。

任何人都可以告诉我将使用哪个引导类或标记?或者我是否必须使用自定义CSS?

提前致谢。

尝试下面的内容,

您可以使用css设置background-image。此外,我建议您使用此功能,因为如果您在响应中生成元素absolute,则会出现问题。

.img-full {
  height: 300px;
  background-image: url('http://www.aegisworld.com/wp-content/uploads/2013/06/65-3.jpg');
  background-repeat: no-repeat;
  background-position: center;
  background-size: 100%;
}
.navbar {
  margin-top: 20px;
}
.navbar.navbar-default {
  background-color: transparent;
  border-color: transparent;
}

这不是Bootstrap功能,您必须将positition:absolute;应用于容器DIV,然后使用<div class="container-fluid" style="padding: 0px;"> <img class="img-responsive center-block header1" src="images/header.jpg" /> <div class='inner'>......</div> </div> .container-fluid { position:relative; } .inner { position:absolute; top:10%; right:20%; } 将适当的顶部和左/右偏移用于内部。

img SRC

如果您想保留import UIKit import WebKit class AboutViewController: UIViewController, WKNavigationDelegate { override func viewDidLoad() { super.viewDidLoad() let webView = WKWebView() webView.navigationDelegate = self let url = NSURL(string: "http://www.yoursite.com") let request = NSURLRequest(URL: url!) webView.loadRequest(request) view = webView } func webView(webView: WKWebView, didStartProvisionalNavigation navigation: WKNavigation!) { // the page begins to load... do what you want here (maybe an indicator to say it is loading...) } func webView(webView: WKWebView, didFinishNavigation navigation: WKNavigation!) { // the page is done loading. do what you need here } } 用户放置图片的方式,这是正确的。否则你可以将它转换为背景,因此,没有必要的相对/绝对定位,但你必须在DIV上设置一个以此图像为背景的大小(宽度和高度)

您需要将图像设置为DIV的背景。您可以使用以下CSS来执行此操作。然后,您可以将内容添加到DIV并相应地设置样式/位置

.container-fluid{
    background:url('images/header.jpg') no-repeat;
    background-size:100% auto;
}

您还需要将DIV的高度设置为图像的高度或所需的高度。
