How to make a div always open next to html?

Question

React

Tell me how to make the div block open only near the closing tag /html when clicked.
That is, there are a bunch of components where you need to call a modal window, inserted at the bottom of each component and, accordingly, when called, it is displayed in the wrong place when viewing the code!
<Modal>Контент< Modal>
