 We hide the default file `<input>` via `opacity` and instead style the `<label>`. The button is generated and positioned with `::after`. Lastly, we declare a `width` and `height` on the `<input>` for proper spacing for surrounding content.

-#### Translating or customizing the strings with SCSS
-
-The [`:lang()` pseudo-class](https://developer.mozilla.org/en-US/docs/Web/CSS/:lang) is used to allow for translation of the "Browse" text into other languages. Override or add entries to the `$custom-file-text` Sass variable with the relevant [language tag](https://en.wikipedia.org/wiki/IETF_language_tag) and localized strings. The English strings can be customized the same way. For example, here's how one might add a Spanish translation (Spanish's language code is `es`):
-
-{{< highlight scss >}}
-$custom-file-text: (
-  en: "Browse",
-  es: "Elegir"
-);
-{{< /highlight >}}
-
-Here's `lang(es)` in action on the custom file input for a Spanish translation:
-
-{{< example >}}
-<div class="custom-file">
-  <input type="file" class="custom-file-input" id="customFileLang" lang="es">
-  <label class="custom-file-label" for="customFileLang">Seleccionar Archivo</label>
-</div>
-{{< /example >}}
-
-You'll need to set the language of your document (or subtree thereof) correctly in order for the correct text to be shown. This can be done using [the `lang` attribute](https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/lang) on the `<html>` element or the [`Content-Language` HTTP header](https://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.12), among other methods.
-
-#### Translating or customizing the strings with HTML
-
-Bootstrap also provides a way to translate the "Browse" text in HTML with the `data-browse` attribute which can be added to the custom input label (example in Dutch):
-
-{{< example >}}
-<div class="custom-file">
-  <input type="file" class="custom-file-input" id="customFileLangHTML">
-  <label class="custom-file-label" for="customFileLangHTML" data-browse="Bestand kiezen">Voeg je document toe</label>
-</div>
