当窗口变小时，Flex 项目不会缩小 [英] Flex items not shrinking when window gets smaller
问题描述
我正在尝试在 CSS flexbox 中放置两个相邻的绘图.我希望它们在调整窗口大小时调整大小.当窗口变大时，它按预期工作，但当窗口变小时，绘图不会缩小.
I'm trying to fit two plotly plots next to each other inside a CSS flexbox. I want them to resize when the window is resized. It works as expected when the window grows, but the plots don't shrink when the window gets smaller.
var trace1 = {};
var trace2 = {};
var plotdiv1 = document.getElementById("plotdiv1");
var plotdiv2 = document.getElementById("plotdiv2");
Plotly.newPlot(plotdiv1, [trace1]);
Plotly.newPlot(plotdiv2, [trace2]);
window.addEventListener("resize", function() {
Plotly.Plots.resize(plotdiv1);
Plotly.Plots.resize(plotdiv2);
});.plot-div {
max-width: 100%;
}
.plot-col {
flex: 0 0 50%;
}
.my-container {
display: flex;
flex-direction: row;
flex-wrap: wrap;
width: 100%;
height: 100%;
}<script src="https://cdn.plot.ly/plotly-latest.min.js"></script>
<body>
<div class="my-container">
<div class="plot-col">
<div id="plotdiv1" class="plot-div"></div>
</div>
<div class="plot-col">
<div id="plotdiv2" class="plot-div"></div>
</div>
</div>

我可能误解了 flexbox 的工作原理，但是如果我用图像替换绘图，它们会按预期缩小.
I am probably misunderstanding how flexbox works, but if I replace the plots with images, they shrink as expected.
我试图调试这个并找到了plotlys内部函数plotAutoSize，它调用window.getComputedStyle并相应地设置绘图大小.我使用 console.log 来查看 window.getComputedStyle 的返回值，当窗口缩小时，它们会卡在"最大尺寸.
I have tried to debug this and found plotlys internal function plotAutoSize, which calls window.getComputedStyle and sets the plot size accordingly. I have used console.log to look at the return values of window.getComputedStyle and they get "stuck" at the largest size when the window shrinks.
如何让绘图缩小以适应窗口并在同一行中彼此相邻?
How can I get the plots to shrink to fit the window and stay next to each other in the same row?
推荐答案
弹性项目的初始设置是 min-width: auto.这意味着默认情况下，弹性项目不能小于其内容.
An initial setting on flex items is min-width: auto. This means that a flex item cannot, by default, be smaller than its content.
您可以使用 min-width: 0 或 overflow 使用除 visible 以外的任何值覆盖此设置.将此添加到您的代码中:
You can override this setting with min-width: 0 or overflow with any value other than visible. Add this to your code:
.plot-col {
min-width: 0;
}
