在此页

gap CSS property sets the gaps ( gutters ) between rows and columns. It is a 简写 for row-gap and column-gap .

The source for this interactive example is stored in a GitHub repository. If you'd like to contribute to the interactive examples project, please clone https://github.com/mdn/interactive-examples and send us a pull request.

CSS 栅格布局 initially defined the grid-gap property. This prefixed property is being replaced by gap . However, in order to support browsers that implemented grid-gap and not gap for grid, you will need to use the prefixed property as in the interactive example above.

句法 

/* One <length> value */
gap: 20px;
gap: 1em;
gap: 3vmin;
gap: 0.5cm;
/* One <percentage> value */
gap: 16%;
gap: 100%;
/* Two <length> values */
gap: 20px 10px;
gap: 1em 0.5em;
gap: 3vmin 2vmax;
gap: 0.5cm 2mm;
/* One or two <percentage> values */
gap: 16% 100%;
gap: 21px 82%;
/* calc() values */
gap: calc(10% + 20px);
gap: calc(20px + 10%) calc(10% - 5px);
/* Global values */
gap: inherit;
gap: initial;
gap: unset;

This property is specified as a value for <'row-gap'> followed optionally by a value for <'column-gap'> 。若 <'column-gap'> is omitted, it’s set to the same value as <'row-gap'> .

<'row-gap'> and <'column-gap'> are each specified as a <length> 或 <percentage> .

值

<length>

Is the width of the gutter separating the grid lines.
