grid-row-start
CSS property specifies a grid item’s start position within the grid row by contributing a line, a span, or nothing (automatic) to its grid placement, thereby specifying the inline-start edge of its
grid area
.

/* Keyword value */ grid-row-start: auto; /* <custom-ident> values */ grid-row-start: somegridarea; /* <integer> + <custom-ident> values */ grid-row-start: 2; grid-row-start: somegridarea 4; /* span + <integer> + <custom-ident> values */ grid-row-start: span 3; grid-row-start: span somegridarea; grid-row-start: 5 somegridarea span; /* Global values */ grid-row-start: inherit; grid-row-start: initial; grid-row-start: unset;
This property is specified as a single
<grid-line>
value. A
<grid-line>
value can be specified as:
auto
keyword
<custom-ident>
value
<integer>
value
<custom-ident>
and
<integer>
, separated by a space
span
together with either a
<custom-ident>
or an
<integer>
or both.
auto
1
.
<custom-ident>
If there is a named line with the name '<custom-ident>-start', it contributes the first such line to the grid item’s placement.
注意：
Named grid areas automatically generate implicit named lines of this form, so specifying
grid-row-start: foo;
will choose the start edge of that named grid area (unless another line named
foo-start
was explicitly specified before it).
Otherwise, this is treated as if the integer
1
had been specified along with the
<custom-ident>
.
<integer> && <custom-ident>?
If a name is given as a <custom-ident>, only lines with that name are counted. If not enough lines with that name exist, all implicit grid lines are assumed to have that name for the purpose of finding this position.
An
<integer>
value of
0
is invalid.
span && [ <integer> || <custom-ident> ]
If a name is given as a <custom-ident>, only lines with that name are counted. If not enough lines with that name exist, all implicit grid lines on the side of the explicit grid, corresponding to the search direction, are assumed to have that name for the purpose of counting this span.
If the <integer> is omitted, it defaults to
1
. Negative integers or 0 are invalid.
<custom-ident>
cannot take the
span
值。
