One of the props (onAccept) is a function, this function will be called after the user has clicked the accept button. It is called with an object containing a boolean property `acceptedByScrolling` to indicate if the acceptance was triggered by the user scrolling You can provide a function like so:
If the decline button is enabled then the (onDecline) prop function can be used, this function will be called after the user has clicked the decline button. You can enable the button and provide a function like so:
react-cookie-consent exports a function called `resetCookieConsentValue`. You can use it in order to remove cookie in client-site:
```js
import CookieConsent, { Cookies, resetCookieConsentValue } from "react-cookie-consent";
console.log(resetCookieConsentValue());
```
That option would be interesting if you want to allow user to change their consent. If you want to show again the consent bar, you must force "visible" prop to show again the bar.
| location | string, "top", "bottom" or "none" | "bottom" | Syntactic sugar to easily enable you to place the bar at the top or the bottom of the browser window. Use "none" to disable. |

When checking the cookie it'll do it in reverse. If the regular cookie exists, it'll use that. If no regular cookie exists it'll check whether the legacy cookie exists. If both are non-existent no consent was given.

You can provide styling for the bar, the button and the content. Note that the bar has a `display: flex` property as default and is parent to its children "content" and "button".
The styling behaves kind of responsive. The minimum content width has been chosen to be "300px" as a default value. If the button does not fit into the same line it is wrapped around into the next line.
You can style each component by using the `style`, `buttonStyle` and `contentStyle` prop. These will append / replace the default styles of the components.
You can pass predefined CSS classes to the components using the `containerClasses`, `buttonClasses` and `contentClasses` props. The example below uses bootstrap classes:
You can make the cookiebar disappear after scrolling a certain percentage using acceptOnScroll and acceptOnScrollPercentage.
It is legal in some use-cases, [Italy](https://www.garanteprivacy.it/web/guest/home/docweb/-/docweb-display/docweb/9679893) being one of them. Consult your legislation on whether this is allowed.
```js
<CookieConsent
acceptOnScroll={true}
acceptOnScrollPercentage={50}
onAccept={(byScroll) => {
alert(`consent given. \n\n By scrolling? ${byScroll}`);
