问题描述
我正在尝试构建一个网站模板，其中主要的#content div为屏幕宽度的75％，并以页面为中心，但我有时还希望包含可覆盖视口整个宽度的部分.我完成此操作的方法是在这些部分上应用一类.full-width，该类通过将width设置为100vw来覆盖#content div的边距，以及一些其他属性，您可以在下面的CSS中看到
I'm trying to build a website template where the main #content div is 75% the width of the screen, and centered on the page, but I also want to occasionally have sections that span the full width of the viewport. The way I've accomplished this is by applying a class of .full-width on these sections that overrides the margins of the #content div by setting the width to 100vw, as well as some other properties that you can see in the CSS below.
问题是，当页面上有足够的内容以显示垂直滚动条时，滚动条的宽度将包括在视口宽度的计算中，因此内容会隐藏在滚动条的后面.
The problem is that, when enough content is on the page that vertical scrollbars appear, the width of the scrollbars is included in the calculation of the viewport width, so content gets hidden behind the scrollbars.
有没有解决这个问题的方法，或者是一种完全不同且更好的方法来完成我要完成的工作?
Is there a way around this problem, or a completely different and better way to do what I'm trying to accomplish?
#content {
width: 75%;
margin: 0 auto;
}
.full-width {
width: 100vw;
position: relative;
left: calc(-50vw + 50%);
box-sizing: border-box;
}
.full-width img {
width: 100%;
}<div id="content">

<!-- content -->推荐答案
您可以通过默认值使用全角，并且当#content > p使用width: 75%时(现在您不需要设置vw，宽度将自动调整)
You can have the full-width by default and when for #content > p use width: 75% (Now you won't need to set vw, the width will auto-adjust)
请注意，将整个#content的 width 设置为75％，然后在它们之间使用全角div会使事情变得不必要地复杂-尽管使用的 hacky 解决方案可以执行负边距和定位.
Note that setting width 75% for the whole #content and then having full-width divs in between makes things needlessly complex - though hacky solutions using negative margins and positioning can be done.
请参见下面的演示
#content > p{
width: 75%;
margin: 0 auto;
}
.full-width {
width: 100%;
box-sizing: border-box;
}
.full-width img {
width: 100%;
}<div id="content">
