# Highlight directive
Adds highlighting to selected sections of an HTML element's content.
## Basic Usage
```HTML
<div
[adf-highlight]="dance"
adf-highlight-selector=".highlightable"
adf-highlight-class="greenHighlight"
>
<div class="highlightable">You can dance if you want to</div>
</div>
```
## Class members
### Properties
| Name | Type | Default value | Description |
| -- | -- | -- | -- |
| adf-highlight-class | `string` | "adf-highlight" | CSS class used to apply highlighting. |
| adf-highlight | `string` | "" | Text to highlight. |
| adf-highlight-selector | `string` | "" | Class selector for highlightable elements. |
## Details
Add `adf-highlight` with a search term to an element to highlight occurrences
of that term in its content. For example:
```HTML
<div [adf-highlight]="'dance'" adf-highlight-selector=".highlightable">
<div class="highlightable">
You can dance if you want to
</div>
</div>
```
...will result in the word "dance" being highlighted. Note that you must also
specify `adf-highlight-selector`, a CSS selector that specifies which
elements can have their contents highlighted.
If the search string contain spaces then each section between the spaces will
be treated as a separate item to highlight. For example, you could use this to
highlight all occurrences of words in a list.
The highlighting works by adding an HTML &lt;span> element around the
selected text. The &lt;span> includes a CSS class; this defaults to
"adf-highlight" but you can supply your own class using the `adf-highlight-class`
property:
```HTML
<div
[adf-highlight]="'dance'"
adf-highlight-selector=".highlightable"
adf-highlight-class="myGreenHighlight">
<div class="highlightable">
You can dance if you want to
</div>
</div>
```
