css - 如何让按钮留在同一个盒子里？

Question

我创建了一个按钮，但每当我缩小窗口时，该按钮就无法使用。它看起来不太好。我想知道如何让我的按钮留在盒子里。查看图片以更好地理解。我提供了按钮的 CSS。我不确定如何为这个问题实现一个好的和有效的解决方案。我能够通过将宽度更改为 100% 来解决我的问题。现在我的信从我的底部被切断了。请看图!

Answer 1

.button {
    box-sizing: border-box; /* Include padding within the button's width */
    width: 100%; /* Made the button the full width of its parent */
    padding: 0 22px; /* Add 22 pixels of padding to the left and right of the button */
}

你可能不需要填充，所以你可以这样做:

button {
    width: 100%;
    padding: 0;
}
