Question: My application becomes slow because I make too many calls to the API to retrieve information. I would like to create a large object with all the information shared with all the pages and get them from localStorage so that the application is more fluid. I work in Angular 7 with Ionic 4. thank you in advance.

Answer: 
use **`@media`** rule to specify any style change for mobile windows or larger windows,here the **`max-width`** property is specifies the maximum width of your mobile window.use overflow-y to provide scroll across y-axis

```
@media screen and (max-width: 480px) {
    body{
          overflow-y : scroll;
        }   
}

```
Use media queries, specify on what size you want it to be scrollable and thats it!! You can get some help to use media queries from here:
