    ```

 These methods work for all browsers the same way.
 Both methods can also use an `options` object as an argument instead of coordinates:

 ```js
 window.scrollTo(options);
 window.scrollBy(options);
 ```

 `options` supports three properties:

 ```js
 window.scrollTo({
  top: 100,
  left: 0,
  behavior: "smooth"
 });
 ```

 - `top` -- same as `y`/`pageY`
 - `left` -- same as `x`/`pageX`
 - `behavior` -- determines how the page will scroll:
  - `"smooth"` -- smoothly (not supported in IE and older versions of Safari)
  - `"instant"` -- instantly
  - `"auto"` -- the browser itself chooses (depends on the CSS property [scroll-behavior](https://developer.mozilla.org/en-US/docs/Web/CSS/scroll-behavior))

 ```online
 Demonstration of smooth page scrolling:
 <button onclick="window.scrollBy({ top: 500, left: 0, behavior: 'smooth' })">window.scrollBy({ top: 500, left: 0, behavior: 'smooth' })</button>
 ```

 ## scrollIntoView

 <button onclick="this.scrollIntoView(false)">this.scrollIntoView(false)</button>
 ```

 Like `scrollTo`/`scrollBy`, `scrollIntoView` also takes an `options` object as an argument (it is slightly different):

 ```js
 this.scrollIntoView(options).
 ```

 `options` supports three properties:

 ```js
 this.scrollIntoView({
  behavior: "smooth",
  block: "end",
  inline: "nearest"
 });
 ```

 - `behavior` -- scroll animation (`smooth`, `instant`, `auto`)
 - `block` -- vertical alignment (`start`, `center`, `end`, `nearest`). Defaults to `start`
 - `inline` -- horizontal alignment (`start`, `center`, `end`, `nearest`). Defaults to `nearest`

 ## Forbid the scrolling

 Sometimes we need to make the document "unscrollable". For instance, when we need to cover the page with a large message requiring immediate attention, and we want the visitor to interact with that message, not with the document.
