Answer:

You can do like this example

```
<style>
.watermark {
    position: absolute;
    opacity: 0.25;
    z-index: 1000;
    transform: rotate(300deg);
    -webkit-transform: rotate(300deg);
    width: 150%;
}

```

```
<div class="watermark">
<p>WATERMARK</p>
<img t-att-. src="'/module_name/static/src/img/image_name.png'" />
</div>

```
