无法去除div的紫色虚线区域

Question

学习了一些 CSS 和 Flexbox 之后，我正在尝试构建一个 Landing 宣传册网站。在构建一个的过程中，我遇到了一个我无法独自解决的问题。 我试图通过让

Col

元素或

Row

元素延伸来删除紫色虚线区域。尽管付出了努力，紫色虚线区域并没有消失。我应该添加一些 CSS 吗？我希望通过填充它来使其看起来有点居中对齐。由于存在多个依赖项，我无法在代码片段上运行代码，但我希望屏幕截图能有所帮助。

Answer 1

所以这里有几个解决方案：

• 你必须用

  width: 100%

  制作这个容器，这样容器将占据父容器的所有空间，并且不会有任何紫色的东西。
• 另一种解决方案是父节点的

  justify-content: center

  ，这样子节点将位于中心，但紫色的东西从两侧都是均匀的，换句话说，将被分成两半，一个在一开始，一结束。

注意：尽量不要使用固定的

width

/

height

Answer 2

对我来说，检查所有父母的

max-width

/

max-height

帮助我发现其中一个被设置为小于孩子。
