# How to use CSS selector to find location of description block?

In some cases the app may fail to detect product description automatically (due to custom theme structure, or some 3rd party apps installed). In this case, we will need to use CSS selector.

Everything you need to do is entering a CSS selector in the CSS selector field to manually identify the location of description block.

For example, suppose your theme renders the product description with the following code:

```html
<div class="custom-description-block">
  {{ product.description }}
</div>
```

To identify the description block, you could enter `custom-description-block`.

||| If no element is selected by the selector, then tabs/accordions won't show up.
