可滚动框内无法访问的内容

编程问答 2022-08-23

问题描述

我正在使用引导程序和jquery创建一个登录屏幕，其中必须对访问卡进行集中。

问题是，当出现垂直滚动条时，滚动到顶部不会显示所有内容，并且无法访问Facebook按钮（取决于高度，谷歌也是如此）。

为补偿导航栏的高度，我在主体和父div上测试了填充顶，但没有成功。

我还尝试在卡之前添加带有clearfix的br，但它不起作用。

解决方法

我已从包含div的align-items-center中删除，并将m-auto添加到卡中。

现在我添加了一个新的Class来防止Card扩展到最大高度，HTMl中的Class和新的CSS都标有注释。我将尝试进一步研究并找出发生这种情况的确切原因，但是您可以尝试一下，看看它是否可以解决您页面上的问题。在代码段中确实如此。

@app.get("/luchshie-avtori")
async def best_authors():
    print('test ping')
    return requests.get('',params={'return': 'json'}).json()

@charset "UTF-8";

html,.small-text *
{
  font-size: 0.8rem;
  font-weight: 400;
}
/*This is the new CSS*/
.display-area{
  max-height: 80%;
}
