CSS border-left-style Property

The CSS border-left-style property is used to set the style of an element's left border.

The border-left-style property is specified as a single keyword chosen from those available for the border-style property. The border-style property is used to set the style for all four sides of an element, but border-left-style sets a style only for the left border.

The default width of the left border is medium. It can be changed by using either the border-left-width or border-width properties.

Not all browsers render the styles in the same way. Chrome, for instance, currently renders the dots as rectangular dots, not circular ones.

The specification does not specify the amount of spacing between the dots and the dashes.

The specification does not define how borders of different styles connect in the corners.

Initial Value none
Applies to All elements. It also applies to ::first-letter.

Version CSS1
DOM Syntax object.style.borderLeftStyle = "solid";

Syntax

border-left-style: none | hidden | dotted | dashed | solid | double | groove | ridge | inset | outset | initial | inherit;

Example

<!DOCTYPE html>
<html>
  <head>
    <style>
      p {
      border-left-style: solid;
      }
      div {
      border-left-style: dotted;
      }
    </style>
  </head>
  <body>
    <p> Example with solid border-left-style.</p>
    <div>Example with dotted border-left-style.</div>
  </body>
</html>

Now let’s see an example where all the style values are separately used in order to see the difference between them:

Depending on the value of the border-color, the effects of groove, ridge, inset and outset values can be changed.

Example

<!DOCTYPE html>
<html>
  <head>
    <title>Title of the document</title>
    <style>
      body {
      background: #c9c5c5;
      font-size: 20px;
      text-align: center;
      }
      main div {
      display: flex;
      align-items: center;      
      justify-content: center;
      color: black;
      padding-top: 30px;
      padding-bottom: 30px;
      width: 200px;
      height: 100px;
      margin: 15px;
      font-weight: bold;
      background-color: #8ebf42;
      border: 10px solid;
      }
      .flex-center {
      display: flex;
      justify-content: center;
      }
