CSS grid - grid-column-start

CSS grid-column-start property defines the starting position of a grid item within the grid columns by specifying a line, a span, or relying on automatic placement. It defines block-start edge of the grid area.

Possible Values

  • auto − It automatically determines the position of the grid item within the grid layout. Deafult span of 1.

  • <custom-ident> − If there's a line labelled with '<custom-ident>-start' or '<custom-ident>-end,' the grid item will be positioned along that line.

    • When using named grid areas, implicit lines are created. The grid-column-start: foo; specifies the start edge of the named region, unless explicitly specified by lines such as foo-start.

  • <integer> && <custom-ident>? − If a name is given, only lines with that name are considered. If there are insufficient lines with that name, all grid lines are processed as if they have that name in order to determine the correct position. An <integer> value of 0 is not valid.

  • span && [ <integer> || <custom-ident> ] − When a name is specified as a custom-ident, only lines with that name get considered.If there insufficient lines with that name, we consider all the grid lines on the relevant side of the grid to have that name for counting purposes. If the <integer> is not specified, the default value is 1. Negative numbers or 0 are not allowed.

Applies to

Grid items and absolutely-positioned boxes whose containing block is a grid container.

DOM Syntax

object.style.gridColumnStart = "auto|<custom-ident>|<integer> && <custom-ident>?|span && [ <integer> || <custom-ident> ]";

CSS grid-column-start - auto Value

The following example demonstrates that grid-column-start: auto property automatically placed grid items in a same order in which they appear in the HTML code −

<html>
<head>
<style>  
   .grid-container {
      display: grid;
      grid-template-columns: auto auto auto;
      color: white;
      text-align: center;
      width: 360px;
      background-color: lightgreen;
   }
   .grid-container > div {
      background-color: red;
      margin: 5px;
      padding: 5px;
   }
   .grid-column-item1 {
      grid-column-start: auto;
   }
</style>
</head>
<body>
   <div class="grid-container">
      <div class="grid-column-item1">Grid item 1</div>
      <div>Grid item 2</div>
      <div>Grid item 3</div>
      <div>Grid item 4</div>
      <div>Grid item 5</div>
      <div>Grid item 6</div>
   </div>
</body>
</html>

CSS grid-column-start - <custom-ident>

The grid-template-columns: [a] 1fr [b] 1fr [c] 1fr; property creates three columns named a, b, and c.

The following example demonstrates that grid-column-start: b property places the first grid item in the second column of the grid −

<html>
<head>
<style>
   .grid-container {
      display: grid;
      grid-template-columns: [a] 1fr [b] 1fr [c] 1fr;
      grid-template-rows: auto;
      background-color: lightgreen;
      padding: 5px;
   }
   .grid-container > div {
      background-color: red;
      border: 2px solid blue;
      padding: 10px;
      text-align: center;
   }
   .grid-item {
      grid-column-start: b; 
   }
</style>
</head>
<body>
   <div class="grid-container">
      <div class="grid-item">Grid Item 1</div>
      <div>Grid Item 2</div>
      <div>Grid Item 3</div>
      <div>Grid Item 4</div>
   </div>
</body>
</html>

CSS grid-column-start - <integer> && <custom-ident>?

The grid-template-columns: [a] 1fr [b] 1fr [a] 1fr [a]; property creates three columns named a, b.

The grid-column-start: 2 a; property, indicates that the second grid item starts at the second `a` named line, which is the third grid line.

The following diagram demonstrates the column layout with line:

Here is an example −

<html>
<head>
<style>
   .grid-container {
      display: grid;
      grid-template-columns: [a] 1fr [b] 1fr [a] 1fr [a];
      grid-template-rows: auto;
      background-color: lightgreen;
      padding: 5px;
   }
   .grid-container > div {
      background-color: red;
      border: 2px solid blue;
      padding: 10px;
      text-align: center;
   }
   .grid-item {
      grid-column-start: 2 a;     /* The second `a` named line, which is the third grid line.*/
   }
</style>
</head>
<body>
   <div class="grid-container">
      <div>Grid Item 1</div>
      <div class="grid-item">Grid Item 2</div>
      <div>Grid Item 3</div>
      <div>Grid Item 4</div>
   </div>
</body>
</html>

CSS grid-column-start - span Value

The following example demonstrates that grid-column-start: span 2 property specifies that the second grid item spans two columns −

<html>
<head>
<style>  
   .grid-container {
      display: grid;
      grid-template-columns: auto auto auto;
      color: white;
      text-align: center;
      width: 300px;
      background-color: lightgreen;
   }
   .grid-container > div {
      background-color: red;
      margin: 5px;
      padding: 5px;
   }
   .grid-item {
      grid-column-start: span 2;
   }
</style>
</head>
<body>
   <div class="grid-container">
      <div>Grid item 1</div>
      <div  class="grid-item">Grid item 2</div>
      <div>Grid item 3</div>
      <div>Grid item 4</div>
      <div>Grid item 5</div>
   </div>
