How can you select the first and the last TD
in a row?
tr > td[0],
tr > td[-1] {
/* styles */

You could use the :first-child
and :last-child
pseudo-selectors:
tr td:first-child,
tr td:last-child {
/* styles */
}
This should work in all major browsers, but IE7 has some problems when elements are added dynamically (and it won't work in IE6).
You can use the following snippet:
tr td:first-child {text-decoration: underline;}
tr td:last-child {color: red;}
Using the following pseudo classes:
:first-child means "select this element if it is the first child of its parent".
:last-child means "select this element if it is the last child of its parent".
Only element nodes (HTML tags) are affected, these pseudo-classes ignore text nodes.
You could use the :first-child and :last-child pseudo-selectors
:
tr td:first-child{
color:red;
}
tr td:last-child {
color:green
}
Or you can use other way like
// To first child
tr td:nth-child(1){
color:red;
}
// To last child
tr td:nth-last-child(1){
color:green;
}
Both way are perfectly working
If you use sass(scss) you can use the following snippet:
tr > td{
/* styles for all td*/
&:first-child{
/* styles for first */
}
&:last-child{
/* styles for last*/
}
}
If the row contains some leading (or trailing) th
tags before the td
you should use the :first-of-type
and the :last-of-type
selectors. Otherwise the first td
won't be selected if it's not the first element of the row.
This gives:
td:first-of-type, td:last-of-type {
/* styles */
}
You can use
table tr td:first-child { css here } for First Child and
table tr td:last-child { css here } for last Child.
