CSS Attribute Selectors
CSS attribute selectors are used to select and style HTML elements with a specific attribute or attribute value, or both.
Attribute selectors are enclosed in square brackets [].
CSS has the following attribute selectors:
[attribute]- Select elements with the specified attribute[attribute="value"]- Select elements with a specific attribute and an exact value[attribute~="value"]- Select elements with an attribute value containing a specific word[attribute|="value"]- Select elements with the specific attribute, whose value can be exactly the value, or start with the value followed by a hyphen (-)[attribute^="value"]- Select elements whose attribute value starts with a specific value[attribute$="value"]- Select elements whose attribute value ends with a specific value[attribute*="value"]- Select elements whose attribute value contains a specific value
Tip: The attribute selectors are case-sensitive by default. To perform a case-insensitive match, add an i before the closing bracket. Example: [attribute="value" i].
CSS [attribute] Selector
The [attribute] selector is used to select elements with the specified attribute.
The following example selects all elements with a target attribute:
Example
a[target] {
background-color: yellow;
}
CSS [attribute="value"] Selector
The [attribute="value"] selector is used to select elements with a specific attribute with an exact value.
The following example selects all elements with a target="_blank" attribute:
Example
a[target="_blank"] {
background-color: yellow;
}
CSS [attribute~="value"] Selector
The [attribute~="value"] selector is used to select elements with an attribute value containing a specific word.
The following example selects all elements with a title attribute that contains a space-separated list of words, one of which is "flower":
Example
[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 specific attribute, whose value can be exactly the specific value, or start with the specific 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;
}
