Size bigger than children

[tillbecks]

Hello, i have the issue, that the component has the width of the whole screen, even if its children-component doesn't.
That makes the hole screen to the right of the children component clickable (if its placed on the left edge).
Is there a fix for it? It seems that I can't change the size of the component via css..
Thanks in advance

@tillbecks for me helped adding this style to global styles of the app
input[type="file"]{
width: 100%;
}
