How to use Horizontal scroll container inside a grid item?

Question

Unable to use Horizontal scroll container inside a grid item. Grid item width gets expanded when a scroll container is inserted. Even scroll container unable to scroll horizontally. When I define a fixed width for the scroll container then only it is working but I want a responsive result. Can anyone please help me with this?

Here is the code snippet.

.grid-container {
            display: grid;
            grid-template-columns: 1fr 3fr 1fr;
            grid-gap: 10px;
        }

        .grid-container>div {
            border: 2px dotted black;
            padding: 10px;
        }

        .code_container {
            padding: 10px;
            margin: 10px 0;
            overflow-x: scroll;
            overflow-y: hidden;
            white-space: nowrap;
            background-color: black;
            color: white;
        }

        .code {
            display: inline-block;
        }

<div class="grid-container">

Finally I have resolved the issue. Just need to include these lines inside container:

min-width: 0;
overflow: auto;

        .grid-container {
            display: grid;
            grid-template-columns: 1fr 3fr 1fr;
            grid-gap: 10px;
        }

        .grid-container>div {
            border: 2px dotted black;
            padding: 10px;
            /* Auto scroll horizontally */
            min-width: 0;
            overflow: auto;
        }

        .code_container {
            padding: 10px;
            margin: 10px 0;
            overflow-x: scroll;
            overflow-y: hidden;
            white-space: nowrap;
            background-color: black;
            color: white;
        }

        .code {
            display: inline-block;
        }

<div class="grid-container">

        <div class="left">
            Lorem ipsum, dolor sit amet consectetur adipisicing elit. Quibusdam delectus ipsum quidem recusandae, optio
            eos dolorem suscipit commodi.
        </div>

        <div class="main">

            <div class="code_container">

                </div>
            </div>

        </div>

Answer 2

Unless content is set to absolute, parent div will keep growing to fit its contents size. This will make your black box (code container) grow. To prevent it, set positioning of code_container's child(.code) to absolute.

.code {
   display: inline-block;
   position: absolute;
}

But now, code's content jumps out from code container. To prevent this, give .code a fixed width. In your case, give 100%.

.code {
    display: inline-block;
    position: absolute;
    width: 100%;
}

But still nothing will change because it takes it's 100% width compared to the width of the body. To prevent this, set .code's parent (.code_container) position: relative;. Now because .code's parent is positioned relative, code will calculate it's 100% width relative to .code_container's width.

Now you should be able to do horizontal scrolling and it is responsive! But the horizontal scroll bar is covering the content. So give .code_container a min-height (about 30px in your case).

Tested in chrome and firefox. Works fine!

.grid-container {
  display: grid;
  grid-template-columns: 1fr 3fr 1fr;
  grid-gap: 10px;
}

.grid-container>div {
  border: 2px dotted black;
  padding: 10px;
}

.code_container {
  padding: 10px 20px;
  margin: 10px 0;
  overflow-x: scroll;
  overflow-y: hidden;
  white-space: nowrap;
  background-color: black;
  color: red;
  position: relative;
  min-height: 30px;
}

.code {
  display: inline-block;
  position: absolute;
  width: 100%;
}
