# Borderless Window Tips

## Titlebar

You can assign title with [`.assign.title`](../../js_api/un_assign/#assigntitlehtml-object).
For window controls, you can use [`.window.minimize`](`../../js_api/window/#minimize`), [`.window.toggle_maximize`](`../../js_api/window/#toggle_maximize`), [`.window.close`](`../../js_api/window/#close`), [`.window.toggle_always_on_top`](`../../js_api/window/#toggle_always_on_top`).

## Movable

To make some regions _like titlebar_ movable, you can use [`*[app-region="move"]`](`../../html_css_api/app_region/#move`).

## Resizable

To make some regions _like corner of window_ resizable, you can use [`*[app-region="nw-resize"]`](`../../html_css_api/app_region/#nw-resize`).
