請搜尋sticky footer 有很多css就能做掉的方式 在能夠只顧支援flexbox的情況 我是用這個超清爽的方式 連結
将footer固定在页面底部的实现方法
同求,之前采用 JS 动态计算,踩过不少坑。后来直接改为中间 content
设了个最小高度
footer: function() { var footerHeight = 0, footerTop = 0, $footer = $(".footer"); positionFooter(); //定义positionFooter function function positionFooter() { //取到div#footer高度 footerHeight = $footer.height(); //div#footer离屏幕顶部的距离 footerTop = ($(window).scrollTop() + $(window).height() - footerHeight) + "px"; /* DEBUGGING STUFF console.log("Document height: ", $(document.body).height()); console.log("Window height: ", $(window).height()); console.log("Window scroll: ", $(window).scrollTop()); console.log("Footer height: ", footerHeight); console.log("Footer top: ", footerTop); console.log("-----------") */ //如果页面内容高度小于屏幕高度,div#footer将绝对定位到屏幕底部,否则div#footer保留它的正常静态定位 if (($(document.body).height() + footerHeight) < $(window).height()) { $footer.css({ position: "absolute", top: footerTop, }); } else { $footer.css({ position: "static" }); } }
bootsrap官网下面有一个插件 好像是handroom(具体忘记了)用于固定header的,footer应该也可以
谢谢大家,问题解决了,方法有好多
但是我在html中用的margin太多了,导致页面无法完美100%显示⊙﹏⊙b汗
最后用padding加上sticky footer的方法解决了

参考2
参考3
JS根据document的scrollTop与document.height-window.height的差,改footer的position:是relative还是fixed;~

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.

PHP performance optimization can be achieved through the following steps: 1) use require_once or include_once on the top of the script to reduce the number of file loads; 2) use preprocessing statements and batch processing to reduce the number of database queries; 3) configure OPcache for opcode cache; 4) enable and configure PHP-FPM optimization process management; 5) use CDN to distribute static resources; 6) use Xdebug or Blackfire for code performance analysis; 7) select efficient data structures such as arrays; 8) write modular code for optimization execution.
