How to Remove an Element from the Flow

How to remove an element from the flow?

None?

I mean, other than removing it from the layout entirely with display: none, I'm pretty sure that's it.

Are you facing a particular situation in which position: absolute is not a viable solution?

Removing Element from Document Flow

Using position: static with display: block seems to work for me. This does make the tool tip appear at the top of the div, however:

const option = document.getElementById('option')

document.getElementById('dropdown').addEventListener('click', function(){

  option.style.maxHeight = option.scrollHeight + 'px'

})

#dropdown {

  position: relative;

  overflow: hidden;

  box-sizing: border-box;

  border: solid red 3px;

}

#label {

  padding: 50px;

}

#option {

  max-height: 0;

  transition:

    .5s max-height;

}

#option:hover {

  background: skyblue;

}

#checkbox {

    /* display: block; */

    width: 100%;

    /* height: 11px; */

    position: absolute;

    pointer-events: none;

    bottom: 0;

    padding: 0;

    opacity: 0;

    margin: 0;

    background-color: #0f0f0f;

    width: 5px;

    left: 50%;

}

#checkbox {

}

<form>

  <div id='dropdown'>

    <div id='label'>Subject</div>

    <div id='option'>Last Option</div>

    <input id='checkbox' type='checkbox' required />

  </div>

  <input type='submit' />

</form>

CSS: Position: Absolute Not Applying - Remove Element from Flow

Seems the sidebar is set to position: relative via div.sidenav.open, div.sidenav.closed in layout.css, which I assume is done by a library. Force it to be position: absolute by either increasing the specificity

div.sidenav.side-bar.closed,
div.sidenav.side-bar.open {
  position: absolute;
}

or use !important

.side-bar {
  position: absolute !important;
}

Remove an element from page flow similiar to a fixed position

Depending what else you have on the page, this might do the trick.

body {
    height:100%;
    width:100%;
    overflow:hidden;
}

nav{
    width:98px;
    height:750px;
    background:blue;   
    position:absolute;
}

If you want other elements to overflow the body, use this code.

<div class="wrapper">
    <nav></nav>
</div>

body {
    height:100%;

}

.wrapper {
    position:absolute;
    top:0;
    bottom:0;
    width:100%;
    overflow:hidden;
}

nav{
    width:98px;
    height:750px;
    background:blue;   
    position:absolute;
}

Remove HTML element completely just by using CSS?

You cannot remove an element from the DOM tree using CSS. You can only prevent it from being rendered in the layout with display: none; doing so does not prevent it from responding to events or cause it to be ignored by CSS selectors such as + and :nth-child(). You won't be able to interact with an element that's not there so you wouldn't be able to trigger events the usual way, but its "essence" remains, so to speak.

React Flow: How to remove an element?

I was able to accomplish the end result I wanted by creating this function:

const deleteNode = (id) => {
  setElements((els) => removeElements([elements[id]], els));
};

And passing this into the OnClick:

onClick={() => deleteNode(0)}

Changing 0 for what ever index the element you wish to remove from the array is

What are the CSS properties that get elements out of the normal flow?

Only the following properties affects the normal flow of any given element:

• float: right|left
• position: absolute|fixed

Just for completeness:

• display: none removes the element from the flow (strictly speaking the element will not have a flow order)

• position: relative does not change the flow order of the element, but changes its position relative to the normal flow position.

• visibility: hidden will maintain the element on the flow but will not render it to the viewport.

How can I get an HTML element to remove from the regular document flow and be relatively positioned?

You will need 'position:absolute;' to achieve this.

Have a look at this example: http://jsfiddle.net/zfUxP/

.wrapper {
    position: relative;
    padding-left: 50px;
}
.favoritesbutton {
    position: absolute;
    left: 0;
    top: 0;
}

The key lays in setting the wrapper to position: relative to serve as a reference for the absolute positioning of the child favoritesbutton
