My goal for this that clicking ‘More’ will cause a hidden box to appear above the parent-Button, and have its own margin above and below. Squeezing itself in. It sort of does that, but its bottom margin does not push the parent-button down. Instead, it pushes down on the height of the parent-button. I tried making the ‘More’ hidden box from SPAN to a P but no change. Tips?

<button type="button" id="0" onclick="bgr(this.id); mor(this.id);abv(this.id);" aria-pressed="false" aria-expanded="false" aria-controls="toggletext">

<span id="toggletext_0">ABOVE to show</span>
</button>
I’m not too sure what you’re going for visually, but replacing display: block with display:inline-block from .showabove produces a much more visually appealing result… Although I’m not sure if that’s what you’re looking for
I temporarily changed .showabove to display:inline-block as suggested and had a modest improvement. But, this revealed box continues to influence the height of the parent element (button). It’s also creating an odd gap of one line in the text. Also, using nth-child to target and conceal the hide/show box kills the entire function.
A few tweaks, but the hide/show element has margins and line-height that should affect layout?
And still puzzled that the CSS is not concealing the hide/show element?
NOTE: The limited ability to influence reflow is baked into browsers. Now, if you want LESS reflow to stop “layout jank” on page load, that’s different. But in this case, I need for the page layout to allow existing elements to slide out of the way when I increase the height of a hidden element.
Not gonna happen except probably with JavaScript, according to the following article…
May have to ask to have this post moved out of HTML/CSS?
