Css 我的形象到哪里去了？flexbox的背景图像
我有一张图片，它应该位于柱子上方和导航栏下方，高度为100 vh。然而，当图像应该存在的空间存在时，图像本身似乎已经消失了。这个URL也指向一个站点，所以它不像是坏了的。我试图弄清楚为什么我的图像没有渲染，以及我能做些什么来帮助它渲染。 使用Flexbox的好方法是什么？flexbox是最有效的方法吗 这是我的HTML：Css 我的形象到哪里去了？flexbox的背景图像,css,image,flexbox,Css,Image,Flexbox,我有一张图片，它应该位于柱子上方和导航栏下方，高度为100 vh。然而，当图像应该存在的空间存在时，图像本身似乎已经消失了。这个URL也指向一个站点，所以它不像是坏了的。我试图弄清楚为什么我的图像没有渲染，以及我能做些什么来帮助它渲染。 使用Flexbox的好方法是什么？flexbox是最有效的方法吗 这是我的HTML： <html lang="en" dir="ltr"> <head> <meta charset="utf-8"> &l

"But I must explain to you how all this mistaken idea of denouncing pleasure and praising pain was born and I will give you a complete account of the system, and expound the actual teachings of the great explorer of the truth, the master-builder of human happiness. No one rejects, dislikes, or avoids pleasure itself, because it is pleasure, but because those who do not know how to pursue pleasure rationally encounter consequences that are extremely painful. Nor again is there anyone who loves or pursues or desires to obtain pain of itself, because it is pain, but because occasionally circumstances occur in which toil and pain can procure him some great pleasure. To take a trivial example, which of us ever undertakes laborious physical exercise, except to obtain some advantage from it? But who has any right to find fault with a man who chooses to enjoy a pleasure that has no annoying consequences, or one who avoids a pain that produces no resultant pleasure?"

您的类.hero的背景url不正确。改用这个： 背景：urlhttps://images.pexels.com/photos/34676/pexels-photo.jpg;
您当前使用的url链接到一个显示图像的站点，而不是您想要的背景图像本身。谢谢，它可以工作，但您是如何获得该图像的？我决定使用另一个图像，但我需要能够执行您所做的操作。使用devtools检查图像将向您显示图像元素及其src属性，即图像本身的url。例如，如果右键单击该url并选择“在新选项卡中打开”，则应仅在新选项卡中看到图像，并且可以使用位置栏中的url从页面链接到图像
