The opposite day, I realized that there’s a pseudo-class in CSS that permits us to focus on an enter when its placeholder is being proven to the consumer: :placeholder-shown. In most cases, I do not like to debris with inputs an excessive amount of; however, in my Dig Deep Health app, I assumed this CSS selector can be a great option to regularly fortify the Person Interface (UI) all over workout efficiency. For every workout, the consumer will have to input their weights and reps. And, I will use :placeholder-shown CSS pseudo-class to emphasise the earlier exercise’s efforts till the consumer enters their present knowledge.
Run this demo in my JavaScript Demos venture on GitHub.
View this code in my JavaScript Demos venture on GitHub.
When a consumer plays an workout, they’re appearing “units”. Every “set” is a composite of a Weight variety and the selection of Reps performed at that weight. The function of resistance coaching is to growth the weights through the years. As such, it may be very lend a hand (possibly very important) to grasp what weight you carried out closing time.
To lend a hand information the consumer, I am masking the former exercise’s weights and reps over the inputs within the present exercise. Through default, the overlay shall be small, grey, and out-of-the-way in order to not be distracting. However, I can then use the :placeholder-shown CSS pseudo-class to emphasise the former efforts whilst the consumer is simply viewing the web page.
This is the impact I need to succeed in:
Understand how the former exercise’s effort rendering begins out giant, daring, and in-your-face. However, as soon as the consumer focuses every enter and begins to kind, the :placeholder-shown CSS pseudo-class turns into invalidated and the overlays recede into the nook and turn into gentle, grey, and out-of-the-way.
This is the code I’ve for this:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8" />
<meta title="viewport" content material="width=device-width, initial-scale=1" />
<hyperlink rel="stylesheet" kind="textual content/css" href="https://www.bennadel.com/weblog/./major.css" />

.set {
align-items: middle ;
show: flex ;
hole: 8px ;
}
.set__panel {
place: relative ;
width: 200px ;
}
.set__input {
width: 100% ;
}
/*
In an effort to help in making the load / reps access more straightforward for the consumer, we are going
to overlay the former exercise's weights / reps on best of the present work-
out's inputs. The preliminary rendering shall be small, gray, and out-of-the-way so
as to be useful however NOT distracting or intrusive.
*/
.set__overlay {
colour: #999999 ;
font-size: 15px ;
line-height: 1 ;
pointer-events: none ;
place: absolute ;
proper: 7px ;
best: 6px ;
transition: all 300ms ease-out ; /* Some razzle-dazzle for the demo. */
}
/*
BUT, we will then PROGRESSIVELY ENHANCE THE UI to be just a little larger and bolder
when the present exercise's inputs have their placeholders being proven.
*/
.set__input:no longer(:focal point):placeholder-shown + .set__overlay {
colour: #333333 ;
font-size: 23px ;
font-weight: bolder ;
proper: 12px ;
best: 11px ;

ASIDE: On this specific context (Dig Deep Health), I feel there’s a little bit of a Person Enjoy (UX) drawback: does the overlay constitute the earlier efforts for the consumer? Or, does it constitute the desired efforts for the present exercise? That is clearly one thing I’ve to take on with my knowledge structure. However, that is neither here-nor-there with regards to the demo. I am simply pondering out-loud.
I feel this can be a neat impact – regardless that, to be transparent, I added the CSS transition belongings in an effort to give the demo some razzle-dazzle. In truth, I dislike maximum animations on the internet and can most probably take away that during my utility. That mentioned, the :placeholder-shown CSS pseudo-class is a fab function; and, I consider it’s going to turn out to be useful when regularly bettering a consumer enjoy.
