cssdiff command is installed. using this command, be enable to see css difference.

adding detection

we have two files.

• x-only.css

• all.css

x-only.css include only about x element, all.css has about x and y.

$ cat data/x-only.css
x {
  color: black;
  display: none;
}
$ cat data/all.css
x {
  color: black;
  display: none;
}

y {
  color: white;
  display: none;
}

so, cssdiff answered, addition about y.

$ cssdiff data/x-only.css data/all.css
y {
+  color: white;
+  display: none;
}

changing detection

If x’s color is changed, cssdiff tell me that x’s color is changed.

$ cat data/x-color-changed.css
x {
  color: white;
  display: none;
}

y {
  color: white;
  display: none;
}

$ cssdiff data/all.css data/x-color-changed.css
x {
-  color: black;
+  color: white;
}

semantic diff

below files are same meaning of all.css. so, no-difference.

$ cat data/all-separated.css
x {
  color: black;
}

y {
  color: white;
}

x {
  display: none;
}

y {
  display: none;
}
$ cssdiff data/all.css data/all-separated.css

$ cat data/all-squashed.css
x,
y{
  display: none;
}

x {
  color: black;
}

y {
  color: white;
}
$ cssdiff data/all.css data/all-separated.css

$ cat data/all-conflicted.css
x {
  color: white;
  display: none;
}

y {
  color: white;
  display: none;
}

x {
  color: black;
  display: none;
}

y {
  color: white;
  display: none;
}
$ cssdiff data/all.css data/all-conflicted.css

appendix

extra.css has extra information. so, cssdiff notify it.

$ cat data/extra.css
x,
y,
a > b,
a + b{
  display: none;
}

x {
  color: black;
}

y {
  color: white;
}
$ cssdiff data/all.css data/extra.css
a + b {
+  display: none;
}

a > b {
