How Can I Control the Spacing of Dots in Dotted CSS Borders?

Controlling Dot Spacing in Dotted Borders

To increase the space between dots in a dotted border, consider using a gradient technique. This method applies to both horizontal and vertical borders.

Horizontal Borders:

• Set background-image to a linear gradient with a percentage value specifying the proportion of the line occupied by dots, followed by 0% for transparency.
• Adjust background-size to control the dot size and the background-position to place the gradient at the border's bottom.

Vertical Borders:

• Use the same linear gradient technique as above, but change the background-position to "right."

Example Code:

/* Horizontal */
background-image: linear-gradient(to right, black 33%, rgba(255,255,255,0) 0%);
background-position: bottom;
background-size: 3px 1px;
background-repeat: repeat-x;

/* Vertical */
background-image: linear-gradient(black 33%, rgba(255,255,255,0) 0%);
background-position: right;
background-size: 1px 3px;
background-repeat: repeat-y;

By adjusting the percentages in the linear gradient, you can control the ratio of dots to spacing. The background-size property determines the dot size.

Note: This technique allows for multiple dotted borders by utilizing multiple background images.
