我正在尝试使页脚停留在页面底部，并且已经在阅读一些YouTube教程。出于某些奇怪的原因，当我单独尝试使用页脚时它们确实起作用，但是当与其他元素结合使用时，不仅将页脚放在页面底部，而且我也无法获得某些问题我的显示：内联块效果很好。...
我一直在尝试遵循本教程：https://www.youtube.com/watch?v=qlCIXXhSX6Y&t=191s和https://www.youtube.com/watch?v=FGBsGqn7ac8&lc=z22eihehdzrajv13qacdp4334oiod53pnruzdum2ru1w03c010c.1541183153454115
我有一个单独的footer.php，并已包含在我的index.php文件中。...我应该在index.php页面或footer.php中使用我的div ID吗？
这是我的页脚代码：
