All the styling you are about to make is linked with the Grid components.

The first thing to do is to place the input texts better : In the Treeview, click the "GridRow1". In the properties, look for the "Alignement" field and set it up to "ion-align-items-end".
It will place the input text at the bottom of this grid.

Repeat this operation with the "GridRow2" and the "GridRow3"by putting the alignment to "ion-align-items-center".

That make the page responsive : You can switch devices by clicking the smartphone icon at the left of the App Viewer to verify.
