title = "Lazy Loading"
template = "demo.html"
+++
This example shows how to lazily load an element on a page. We start with an initial
state that looks like this:
```html
<div hx-get="/graph" hx-trigger="load">
<img alt="Result loading..." class="htmx-indicator" width="150" src="/img/bars.svg"/>
</div>
```
Which shows a progress indicator as we are loading the graph. The graph is then
loaded and faded gently into view via a settling CSS transition:
```css
.htmx-settling img {
opacity: 0;
}
img {
transition: opacity 300ms ease-in;
}
```
<style>
.htmx-settling img {
opacity: 0;
}
img {
transition: opacity 300ms ease-in;
}
</style>
{{ demoenv() }}
<script>
server.autoRespondAfter = 2000; // longer response for more drama
//=========================================================================
// Fake Server Side Code
//=========================================================================
// routes
init("/demo", function(request, params){
return lazyTemplate();
});
onGet("/graph", function(request, params){
return "<img alt='Tokyo Climate' src='/img/tokyo.png'>";
});
// templates
function lazyTemplate(page) {
return `<div hx-get="/graph" hx-trigger="load">
<img alt="Result loading..." class="htmx-indicator" width="150" src="/img/bars.svg"/>
</div>`;
}
</script>
