Wrapping and shrinking text if needed to fit button - html

For months this is the only problem I haven't been able to solve. I've hired multiple people on Freelancer to help and two gave up, and another said it was impossible.
I'm simply trying to get the text of my buttons to stay within the boundaries of the button. Right now it looks like this.
All I need to do is wrap the text if it's too long to fit the horizontal boundaries of the button, and shrink the text if it's too big to fit within the boundaries of the button. Like this:
I've tried:
Using Fitty, FitText, and other libraries which don't work at all. They'll sometimes make the text too big to fit within the boundaries of the button, and sometimes they'll make all of my text small unnecessarily.
Creating my own function by looking at clientWidth and clientHeight, and shrinking the font as necessary. When I do that, clientWidth of my elements stay the same regardless of the actual size, I've also used getComputedStyle which doesn't seem to calculate properly either.
Paying people. Again multiple people have given up, and I've spent months trying to solve this with no success.
I've created a codepen with a minimally reproducible example showing the problem.
https://codepen.io/TheNomadicAspie/pen/dyRLrej
And here is the code (I've removed all of the unnecessary code, but left in the parent divs of the buttons in case they are affecting whatever is keeping the libraries/my functions/other people from being able to do this).

Edit: To clarify, I need the button to not get larger to fit the text, I need the text to get smaller to fit the button.

This here does the job by wrapping the text and making the box larger, it does however mess up the spacing between the boxes. Took me a few minutes, hope it helps :)
#answer_button_1 {
height: auto;
max-width:30wv;
hyphens: auto;

The Spacing between the buttons can be fixed by removing the following lines from .answers-display:
grid-template-rows: 25% 25% 25% 25%;
height: 100%;

Hmmmm. Yes, this is a tricky one. Using this article as inspiration, I was able to come up with the following solution. The technique used is to start with a really small font size (I have set minSize to 8 for this example) and test whether the text overflows its container; if the text does not overflow, increase the font size by a small amount (I've set step to 0.5) and re-test; then if the text overflows, revert to the previous font size.
Note, however, that it uses regular divs rather than buttons. The solution relies on a set of nested elements, which the button element does not support. Buttons also seem to have some built-in padding or sizing which is difficult to control. I suspect that Fitty and FitText don't work on buttons. I did try swapping the innermost divs with buttons in this snippet, and while it still works fairly well, it's more complicated and doesn't look as good. The only reason to prefer a button over a div is purely a semantic one, so I'd recommend sticking to using divs. Just add your click handler and off you go.
You can try different values for minSize, step and so on to see how that affects the result. Note that because I have used a minSize of 8, there comes a point where very long texts still overflow the button. Setting minSize to 0 avoids this -- the text fits on the button regardless of its length, but for some reason the text doesn't quite fill the button: the bottom padding appears larger. But your results may vary.
const isOverflown = ({ clientHeight, scrollHeight }) => scrollHeight > clientHeight
const resizeText = ({ element, elements, minSize = 10, maxSize = 512, step = 1, unit = 'px' }) => {
(elements || [element]).forEach(el => {
let i = minSize
let overflow = false
const parent = el.parentNode
while (!overflow && i < maxSize) {
el.style.fontSize = `${i}${unit}`
overflow = isOverflown(parent)
if (!overflow) i += step
}
// revert to last state where no overflow happened
el.style.fontSize = `${i - step}${unit}`
})
}
resizeText({
elements: document.querySelectorAll('.button>div>div'),
minSize: 8,
step: 0.5
})

It's a real pity that web standards do not currently provide a mechanism for automatically adjusting font size to fill a fixed size container. There are mechanisms to do it with images, so why not with text? I myself have had regular situations over the years where I have wished this were possible.
I am curious, though, as to why it is so important for you for the buttons to be a fixed size? Doesn't readability become a problem when there's a lot of text, and the font-size gets so small? Would it not be a better solution to simply allow the buttons to grow vertically to contain longer pieces of text? Or even truncate the text at a maximum number of characters or words, and add an ellipsis to indicate that truncation occurred?

SOLVED - Why is this bootstrap card misaligned?

The image and text of this bootstrap card are supposed to be side by side, with the combo title + text centralized in relation to the image. But they are somewhat above the image.
Image of how it looks:
HTML:
<div class="card bg-transparent border-0 text-white mb-3" >
<div class="row g-0">
<div class="col-md-6">
<img src="../assets/images/cp/sobre-cid-1.jpg" class="img-fluid rounded-start img-esq" alt="cid-1">
</div>
<div class="col-md-6">
<div class="card-body">
<h3 class="card-title">TITLE</h3>
<p class="card-text">Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.</p>
</div>
</div>
</div>
</div>
CSS:
.img-fluid.rounded-start {
height: calc(120px + 10vw);
width: 90vw;
object-fit: cover;
}
.img-esq {
border-radius: 0px 30px 30px 0px;
}
.img-dir {
border-radius: 30px 0px 0px 30px;
}
.card-title {
font-family: 'Martel';
font-size: 22px;
padding: 20px;
text-align: left;
font-weight: 600;
}
.card-title-right {
font-family: 'Martel';
font-size: 22px;
padding: 20px;
text-align: right;
font-weight: 600;
}
.card-text {
font-family: 'Martel';
font-size: 14px;
padding-left: 20px;
padding-right: 30px;
text-align: left;
}
.card-text-right {
font-family: 'Martel';
font-size: 14px;
padding-left: 30px;
padding-right: 20px;
text-align: right;
}
Additional info: The card is inside a div that gets the entire page, this is it's CSS:
.bg {
background-image: url(../images/cp/fundo.png);
background-position: center;
background-repeat: repeat-y;
background-size: cover;
margin-top: 0px;
text-align: center;
color: white;
display: flex;
flex-direction: column;
justify-content: center;
}
I mostly looked for margins and paddings. I tried changing padding-top and margin-top to zero, I even looked for this in the item above the bootstrap card, but nothing helped, there was only a br tag between the item above the card and the card itself. I also looked for a margin in the card and everything seems right.
EDIT 1:
I added to .row a display: flex and align-items:center, it is not perfectly centered but maybe I can use it, but there's still a big space in between each card:
EDIT 2:
I added to .row a margin-top: -80px and now the space between cards is good. Not the perfect solution I think but works for now.
To make the text vertically centered in relation to the image, I added margin-top: 60px to the cards' titles, and it pushed them down. Again, not perfect but works for now.
EDIT 3:
I fixed it. The problem was in a part of the CSS code I didn't know influenced the whole page. It was like this:
img {
width: 70%;
height: auto;
margin-top: 15%;
}
I thought it would only influence the class that was above it. Turns out, it influenced all the img tags.
I found out by deleting part by part of the CSS code in Codepen.
The problem may be caused by the calc() function in the height property for the img-fluid.rounded-start class. This function calculates the height of the image based on the size of the viewport, which could be causing the image to be larger or smaller than expected. Try to set fixed values to it.
Also, you can try and use align-items: center in the .bg class, this should align the elements at the center of the div.

Rotate text 90 degrees and vertically center next to wrapped inline text

I am trying to rotate text 90 degrees and vertically center it next to inline wrapped text. I need to keep the text inline so I can left-align the text itself, then center the whole thing when the text wraps.
It seems to work fine in Chrome when the text is on one line and when wrapped. In Firefox it seems to work fine when the text is on one line, but when wrapped, it does not vertically center the rotated text.
It seems like Firefox is not recognizing the height of the wrapped text.
Here is a fiddle showing what I'm working with. https://jsfiddle.net/hemmieweizen/7t5gh91z/12/ Notice on Firefox when you decrease the width of the output and the text wraps, the vertical text does not continue to center.

Try to use a layout like flex; make both <span>Charles Smith</span> and <span>Your Agent</span> direct children of <h2> rather than nested children. Remove the hard-coded position rules from these elements, and let the flexbox manage them for you. You can still refine their positions with mere margin and padding.

How do create a CSS for Adsense banner move under My content

How do create a CSS so that My content is on the left side of the screen and I place the vertical Adsense on the right side, however, the page opens on the smartphone, the Adsense banner move under My content?
You should learn first about Responsive Web Design.
According to this, there are many ways to make a page responsive.
Flexbox, Grid, MediaQueries & ...
I'm showing you an example using FlexBox.
You can also read about CSS Grid here.
And about Media Queries here.
Result: As you can see, if the total width of the two boxes would be over 520px, then it will break into a new line.
const check = () => {
let firstBoxInput = document.querySelector('.first-child-width').value;
let secondBoxInput = document.querySelector('.second-child-width').value;
const firstBox = document.querySelector('.first-child');
const secondBox = document.querySelector('.second-child');
firstBox.style.width = `${firstBoxInput}px`;
secondBox.style.width = `${secondBoxInput}px`;
};
document.querySelector('button').addEventListener('click', check);

Media queries can be used to check many things, such as:
width and height of the viewport
width and height of the device
orientation (is the tablet/phone in landscape or portrait mode?)
resolution
Using media queries are a popular technique for delivering a tailored style sheet to desktops, laptops, tablets, and mobile phones

Vertically align image with dynamic text

So I have a div, whose height I don't know initially. It has two children - an <img> on the left, and a <div> contains some content on the right. The image size is fixed, say 50 by 50. However, the content can be of any size. It may be even one line, in which case it becomes smaller in size compared to the photo. Either way, the parent div has to find out which one is bigger and grow vertically to accommodate both, while ensuring that both are properly centered (taking into account a vertical padding of 5 px).
Also imagine that the content won't wrap below the image, i.e it is a standalone element on the right side (as if floating right).
That is, if the content is say just one line, then the parent div should be of height 50+5*2 = 60px, the img on the left being centred at 5px from top, the content on the right (assume at a margin of 5 px from the left), which here is just one line, centred vertically.
Or say the content is so big that it is 100px high, then the parent div will be 100+5*2 = 110px high. The img will be on the left, at 30px from the top.
Can anyone help me fix the issue?
This is what I came up with: https://jsfiddle.net/fj77eobe/

Place background image 1em from the right?

As far as I can tell, it is not possible to place a CSS background image 1em from the right border of any block, neither is it possible to place a image 1em from the bottom.
The following code places the background image 1em from the left and 2em from the top.
<div class="foo" style="background: url('bar.png') no-repeat 1em 2em">
Some text here
</div>
Is there any way in CSS to specify that the background image should be "this far from the right edge" if the size of the box is dynamic and assuming that you cannot change the HTML?
(Percentages won't work, since the box can change size)
If this is not possible, what is the smallest amount of change you need to make to the HTML?
This is the workaround I came up with:
<style>
div.background
{
float: right;
background: url('bar.png') no-repeat top left;
margin-right: 1em;
width: 16px;
height: 16px;
}
</style>
<div class="foo">
<div class="background" style=""> </div>
Some text here
</div>
The CSS3 background-position spec allows you to change the anchor point from the top left to anything you want. For example, the following will set the lower bottom corner of the image 1em from the right and 2px from the bottom:
background-position: right 1em bottom 2px;
Confirmed to work in:
IE9/10, Firefox 13+, Chrome 26+, Opera 11+, Seamonkey 2.14+, Lunascape 6.8.0
As of April 2013, only IE6-8 and some fringe browsers lack support.
Here's a test page: http://jsbin.com/osojuz/1/edit
Elements with position: absolute; can be positioned by their right edge.
So, if you don't mind a minor change to the html, do this:
<div id="the-box">
<img id="the-box-bg" src="bar.png" />
Text text text text....
</div>
(...)
#the-box {
position: relative;
}
#the-box-bg {
position: absolute;
right: 1em;
z-index: -1;
}
You could of course also use absolute positioning of a second div, with a repeating background. But then you would have to set the size of the (inner) div in CSS.
You could try something like this:
<style type="text/css" media="screen">
#outer {
position: relative;
top: -1em;
left: -1em;
margin: 1em 0 0 1em;
outline: thin solid #F00;
background: url(http://i.stackoverflow.com/Content/Img/stackoverflow-logo-250.png) no-repeat 100% 100%;
}
#inner {
outline: thin solid #0F0;
position: relative;
top: 1em;
left: 1em;
}
</style>
<div id="outer">
<div id="inner">

Edit: Looking forward to CSS 3 background-position.
After some research the actual x pixel length of the background position is always counted from the left side of the element. The only way to make this work (without using other elements) would be to use javascript, calculate the left length given the elements width:
var rightMargin = "10"; // in pixels
var imageWidth = "16";
var left = element.style.clientWidth - imageWidth - rightMargin;
element.style.backgroundPosition = "0px " + left + "px";
