## README

# wc-lazy

allows to optimize the load of images based on `IntersectionObserver`.

## lazy-img

this web-component, mediate the attribute and property `src` create a tag `<picture>` to address the loading of images, `src` represent the behavior of `img[src]` and `img[srcset]` so joint

### normal load

Insert the picture tag, only when the intercession happens.

```
<lazy-img src="/my-img.jpg"></lazy-img>

<picture>
	<img src="/my-img.jpg"/>
</picture>
```

### responsive charge

Insert the picture tag, only when the intercession happens.

```
<lazy-img src="/my-img2.jpg 520w, /my-img3.jpg 720w, /my-img.jpg"></lazy-img>

<picture>
	<source media="(min-width: 720px)" srcset="/my-img3.jpg"/>
	<source media="(min-width: 520px)" srcset="/my-img2.jpg"/>
	<img src="/my-img.jpg"/>
</picture>
```

> The use of picture vs img, picture allows you to add more rules on image selection, example type and it works better with responsive art direction.

### intercepted

every time that `lazy-img` is intercepted the attribute `intercepted` will be defined, for the generation of side effects, this can also be heard as an event.
