## `kt-classes`
|
||||
|
||||
The `kt-classes` attribute allows you to specify CSS classes that will be swapped onto the element that
|
||||
the attribute is on. This allows you to apply [CSS Transitions](https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Transitions/Using_CSS_transitions)
|
||||
to your HTML without resorting to javascript.
|
||||
|
||||
A `kt-classes` attribute value consists of "runs", which are separated by an `&` character. All
|
||||
class operations within a given run will be applied sequentially, with the delay specified.
|
||||
|
||||
Within a run, a `,` character separates distinct class operations.
|
||||
|
||||
A class operation is an operation name `add`, `remove`, or `toggle`, followed by a CSS class name,
|
||||
optionally followed by a colon `:` and a time delay.
|
||||
|
||||
Here are some examples:
|
||||
|
||||
```html
|
||||
<div kt-classes="add foo"/> <!-- adds the class "foo" after 100ms -->
|
||||
<div kt-classes="remove bar:1s"/> <!-- removes the class "bar" after 1s -->
|
||||
<div kt-classes="remove bar:1s, add foo:1s"/> <!-- removes the class "bar" after 1s
|
||||
then adds the class "foo" 1s after that -->
|
||||
<div kt-classes="remove bar:1s & add foo:1s"/> <!-- removes the class "bar" and adds
|
||||
class "foo" after 1s -->
|
||||
<div kt-classes="toggle foo:1s"/> <!-- toggles the class "foo" every 1s -->
|
||||
```
|
||||
|
||||
### Notes
|
||||
|
||||
* The default delay if none is specified is 100ms
