CSS: Change the width according to the level

Hello everybody. I try to make a Custom Node Content Render it goes almost well until a little problem. I would like the end of my boxes to be all on the same level. Do you have any idea how to do this?


As you can see on my screenshot, I don't want my subtrees to stick out of my main trees. thank you.

Note : For the size I use :
```
generateNodeProps={({node, path}) => {
return {
style: {
width: '50vw',
},
...
```
