How can you elevate an HTML element to the front using the "z-index" property or the "append" method?

When working with HTML documents, we often come across various HTML elements like div, p, img, and more.

Many of these elements are dynamically created, especially if helpful CSS such as "position: absolute;" is used.

After every onClick event, it is necessary for the element to be brought to the front of other elements. This can be achieved by using:

element.parentNode.appendChild(element);
or
element.parent().append(element);

Alternatively, you can do it like this:

// For example, using CSS:
$('#ObjId').css('z-index', HighestIndx+1 );

Personally, I prefer using appendChild because adding the z-index property directly to the element can sometimes cause issues.

However, I am unsure which approach is better - using z-index or append/appendChild. So my question is: Which is the better method to use - z-index or append/appendChild? Thank you.

Answer №1

Personally, I prefer using z-index because of its speed and reliability in older browsers. But everyone has their own preferences.

While the article touches on some important points, it might not directly address your specific question.

Answer №2

Adding a child element using appendChild() does not affect the z-index of the elements. It simply appends the new child to the bottom of its parent's children list. To position your div in front of other elements, it is better to utilize the z-index property.
