CSS [attribute~="value"] Selector
The [attribute~="value"] selector is used to select elements with an attribute
value containing a specified word.
The following example selects all elements with a title attribute that
contains a space-separated list of words, one of which is "flower":

[title~="flower"] { border: 5px solid yellow;}

The example above will match elements with title="flower", title="summer
flower", and title="flower new", but not title="my-flower" or title="flowers".

CSS [attribute|="value"] Selector
The [attribute|="value"] selector
is used to select elements with the specified attribute, whose value can be
exactly the specified value, or the specified value followed by a hyphen (-).
Note: The value has to be a whole word, either alone, like
class="top", or followed by a hyphen( - ), like class="top-text".

Example

[class|="top"] { background: yellow;}

the specified value.

starts with "top":
Note: The value does not have to be a whole word!

[class^="top"] {  background: yellow;}

Styling Forms
The attribute selectors can be useful for styling forms without class or ID:

Example

input[type="text"]
{
  width: 150px;

display: block;

margin-bottom: 10px;

background-color: yellow;
}
input[type="button"]
{
  width: 120px;
  margin-left: 35px;
  display: block;
}
