 Adaptive scraping (previously known as automatch) is one of Scrapling's most powerful features. It allows your scraper to survive website changes by intelligently tracking and relocating elements.

 ### The CSS/XPath Selection way
 As you have seen in the example above, first, you have to use the `auto_save` argument while selecting an element that exists on the page, like below
 ```python
-element = page.css('#p1' auto_save=True)
+element = page.css('#p1', auto_save=True)
 ```
 And when the element doesn't exist, you can use the same selector and the `adaptive` argument, and the library will find it for you

 Pretty simple, eh?
 
-Well, a lot happened under the hood here. Remember the identifier we mentioned before that you need to set to retrieve the element you want? Here, with the `css`/`css_first`/`xpath`/`xpath_first` methods, the identifier is set automatically as the selector you passed here to make things easier :)

 Additionally, for all these methods, you can pass the `identifier` argument to set it yourself. This is useful in some instances, or you can use it to save properties with the `auto_save` argument.
