The elements within <header> and <footer> tags will always remain at the top of the page unless specifically

While working on creating semantically correct HTML, I included a header and footer in my document.

The structure of the document looks like this:

...

Currently, the header, main, and footer take up 100% of the height. I want the modal to do the same once a button is pressed.

The issue I'm facing is that even when I set every element's z-index to 0 and the modal's z-index higher than the header and footer, the header and footer remain on top of the modal.

I did find a workaround by giving the header and footer a negative z-index, but I'm not satisfied with this long-term solution. I'm also curious why setting the div's z-index higher than the header and footer does not have any effect.

Answer №1

To achieve the desired movement of #settingsModal, it is essential to assign it a position of absolute. Currently, the element's position is set as default to static, which hinders its ability to move as intended.

According to information from CSS-Tricks:

The z-index property in CSS determines the vertical stacking order of elements that overlap. It specifies which one appears visually closer to the viewer. The z-index property only applies to elements with a position value other than static (which is the default).
