CSS Flexbox incorrect on Firefox and IE - html

I have recently been developing a website using flexbox, and have been doing so on Chrome. The site looks perfect on Chrome (and Safari, according to users) however it has some serious issues when viewed on Firefox and IE. I have tried to look online for documentation on which prefixes to include in my CSS and how to make it appear normal on those browsers, but I truly cannot find a summation or tutorial anywhere. Here is a sample of my CSS code, containing flexboxs that do not display correctly on Firefox and IE -
.header {
padding: 12px;
padding-top: 10px;
padding-bottom: 0px;
margin: 0px;
display: -webkit-box;
display: -moz-box;
display: -ms-flexbox;
display: -webkit-flex;
display: flex;
-webkit-flex-flow: row wrap;
justify-content: space-around;
height: 70px;
background-color: #000000;
}
.header-box {
padding-left: 15px;
padding-right: 15px;
margin: 0;
display: -webkit-box;
display: -moz-box;
display: -ms-flexbox;
display: -webkit-flex;
display: flex;
-webkit-flex-flow: row wrap;
align-content: flex-start;
align-items: flex-start;
height: 70px;
width: 1170px;
background-color: #000000;
}
This code is for a header bar along the top of the site. I thought by including the display: -moz-box; and such, that would allow it to be seen on Firefox, but the formatting is messed up in the sense that the box is not centered but instead along the left side of the screen, and the boxes within the header are all along the top of the parent container rather than on the bottom. Thank you for any insight you may have on this problem!

In only works on webkit browsers because you only use
-webkit-flex-flow: row wrap;
You should use the standard
flex-flow: row wrap;
Otherwise, the initial value row nowrap will be used instead.

Using Flex/CSS with wkhtmltopdf

I've successfully created a list using the following answer with flexbox on my HTML page How to display 3 items per row in flexbox?
I have a need to create a PDF with this data and I'm using wkhtmltopdf (https://wkhtmltopdf.org/) which also works fine however the PDF generated has all my List Items in 1 long column instead of 3 per row.
Looks like the CSS is not being processed when the PDF generation is happening any insight is appreciated.
This worked for me :
.row {
display: -webkit-box; /* wkhtmltopdf uses this one */
display: flex;
-webkit-box-pack: center; /* wkhtmltopdf uses this one */
justify-content: center;
}
.row > div {
-webkit-box-flex: 1;
-webkit-flex: 1;
flex: 1;
}
.row > div:last-child {
margin-right: 0;
}
See https://github.com/wkhtmltopdf/wkhtmltopdf/issues/1522 for more informations.
I resolved this issue using:
equivalent of display:flex; ==> display: -webkit-box;
equivalent of justify-content: space-between; ==> -webkit-box-pack: justify;
Some useful informations coming from:
https://github.com/wkhtmltopdf/wkhtmltopdf/issues/1522
I used autoprefixer in my application to automatically add prefixes. You just need to update browsersList with ie >= 9.
Try to decrease the width of the flex columns. For example when I tried to make 50/50 columns I had to put a width of 49.8% instead of 50%. Hope it helps.
To use flex or boxes while converting to pdf, You need webkit
Example:-
display: flex;
display: -webkit-flex;
for justify-content and align items you have to use
-webkit-align-self: flex-end;
align-self: flex-end;
webkit-justify-content: space-between;
justify-content: space-between;
As fix for Bootstrap 5, working with wkhtmltopdf 0.12.*, I found and completed the following style
<style>
/* Fix wkhtmltopdf compatibility with BS flex features */
.row {
display: -webkit-box;
display: flex;
-webkit-box-pack: center;
justify-content: center;
}
.row>div {
-webkit-box-flex: 1;
-webkit-flex: 1;
flex: 1;
}
.row>div:last-child {
margin-right: 0;
}
/* Fix wkhtmltopdf compatibility with BS tables borders */
/* Requires cellspacing="0" on table to prevent spacing */
table {
border-collapse: separate !important;
}
th,
td {
border-top: none;
border-left: none;
border-right: none;
}
</style>
source saved my day while upgrading from bs 4 to bs 5.
This worked for me:
.row {
white-space: nowrap;
> div {
display: inline-block;
white-space: normal;
}
}

How to fix Flexbox styles in IE 11

I'm using flexbox here - http://marcinzalewski.net/exo/ but I can't fix this for IE 11. Even Microsoft Edge is working fine and IE 11 is only version I need to fix.
My flex-container look like this:
.flex-container {
max-width: 1240px;
display: -webkit-box;
display: -moz-box;
display: -ms-flexbox;
display: -webkit-flex;
display: flex;
-webkit-flex-flow: row wrap;
-webkit-flex-wrap: row wrap;
justify-content: center;
padding: 0;
margin: 0 auto;
list-style: none;
}
And this is my inside elements code:
.offer-element {
width: 250px;
height: 250px;
border-radius: 50%;
margin-top: 60px;
margin-left: 25px;
margin-right: 25px;
}
Now those elements should be centered and fit in few lines, but they all are in the same line and have ~150px instead of 250px each. I tried to add display: -ms-flexbox; but it doesn't work anyway. Normally they are all centered and take 3 lines.
It looks like you're specifying flex-wrap only on webkit. By default flex will fit all items one line. You need to specify flex-wrap: wrap on your container.
IE 11 requires a unit to be added to the third argument, the flex-basis property

Flexbox children rendering wrong in Safari

I have the following HTML and css that works great in Firefox and Chrome to create a 3-column grid of boxes. But, in Safari it takes all the boxes and puts them into 1 row, squishing the width of each one so it will fit instead of allowing the float to push the boxes to a new line.
How can I get it to looks the same in Safari, any ideas?
(note: the html class '.box' is in a loop that dynamically generates boxes based on user input, so the number of boxes is variable)
HTML:
<div id="home-grid">
<div class="box">
Contents of box
</div>
</div>
CSS:
#home-grid {
margin-top: 20px;
float: left;
display: -webkit-box; /* OLD: Safari, iOS, Android browser, older WebKit browsers. */
display: -moz-box; /* OLD: Firefox (buggy) */
display: -ms-flexbox; /* MID: IE 10 */
display: -webkit-flex; /* NEW, Chrome 21–28, Safari 6.1+ */
display: flex; /* NEW: IE11, Chrome 29+, Opera 12.1+, Firefox 22+ */
flex-flow: row wrap;
justify-content: space-between;
width: 100%
}
#home-grid .box {
position: relative;
float: left;
width: 192px!important;
height: 180px;
border: 1px solid #F73987;
margin-bottom: 20px;
overflow: hidden;
}
I was able to get it to work in the latest version of Safari by adding these two lines:
-webkit-flex-flow: row wrap;
-webkit-justify-content: space-between;
see jsfiddle
Just to clarify, Safari still needs the -webkit prefix, according to caniuse.com

Flexbox behaviour goes against its philosophy

I'm new to this topic and read myself into it. I worked through this guide.
In this guide they say:
The main idea behind the flex layout is to give the container the ability to alter its items' width/height (and order) to best fill the available space.
I want Flexbox to use all available space, but obviously right under 2 there is empty space and also enough space for the element 3.
When I take a look at the philosophy of Flexbox I can see not used but available space in my layout.
Am I doing something wrong in my css or is Flexbox broken?
Layout/Output
CSS
.flex-container {
padding: 0;
margin: 0;
list-style: none;
display: -webkit-box;
display: -moz-box;
display: -ms-flexbox;
display: -webkit-flex;
display: flex;
align-items: flex-start;
-webkit-flex-flow: wrap;
}
.flex-item {
background: tomato;
padding: 5px;
width: 300px;
margin-top: 10px;
line-height: 150px;
color: white;
font-weight: bold;
font-size: 3em;
text-align: center;
}
HTML
<ul class="flex-container">
<li class="flex-item">1111111111 1111111111</li>
<li class="flex-item">2</li>
<li class="flex-item">3</li>
<li class="flex-item">4</li>
<li class="flex-item">5</li>
<li class="flex-item">6</li>
</ul>
Flexbox is primarily a one-dimensional layout mode. It lets you distribute & size elements responsively, in just a single axis (horizontal or vertical), and then it supports basic alignment/stretching in the other axis.
flex-wrap: wrap can make it look two-dimensional, but really it just lets you split your flex items into "lines", where each "line" is like a one-dimension flexbox. And the lines don't overlap (or really interact at all).
So, in your diagram, the "3" element doesn't fill in the empty space because it's in a separate flex line from where the empty space is, and the flex lines cannot overlap.
To achieve what you want in pure CSS, I think you'll need CSS Grid, specifically with grid-auto-flow: dense. This spec is still under active development, though, and browsers have mixed levels of implementation, so it's not ready for use in production websites yet.
Yes, your CSS is slighty wrong
JSFiddle Demo
CSS
.flex-container {
padding: 0;
margin: 0;
list-style: none;
display: -webkit-box;
display: -moz-box;
display: -ms-flexbox;
display: -webkit-flex;
display: flex;
flex-wrap: wrap; /* here */
}
.flex-item {
display: -webkit-box;
display: -moz-box;
display: -ms-flexbox;
display: -webkit-flex;
display: flex;
background: tomato;
padding: 5px;
width:300px;
margin-top: 10px;
line-height: 150px;
color: white;
font-weight: bold;
font-size: 3em;
text-align: center;
}
However, on further discussion it appears that what you are trying to achieve is not possible (AFAIK) with flexbox.
I expect element 3 to move under 2, so all the empty space is used
Accordingly, I think a JS solution like Masonry.Js would be the recommended solution.

CSS max-width causes too much white space if inline element exceeds max-width and splits into two lines

I am trying to style a li elements to dynamically fit its text content with equal spacing between the li's but cannot seem to accomplish this.
The result currently looks like:
I want the white spaces between the li's to be consistent but the overall li's to be dynamic widths but not exceeding a certain width: (Because there are two different ul's they are styles with different paddings so that is why the space sizes are different between the left menu and right menu, but each li is consistently spaced in the respective ul's)
The css is (arbitrarily):
li{
display: inline-block;
max-width: 95px;
padding: 5px 10px;
etc....
}
I'm trying to accomplish this using css, avoiding JavaScript or html markup if possible. Thank you.
If you want the whitespace between the elements to be the same, ie. smaller headings will have smaller menu items like in your images then you're out of luck. I don't think you can do it without JavaScript.
If you will setting with uniform width menu items then that's fairly easy to accomplish, just set the <li>s to 100%/(number of menu items) and float them.
li {
float:left;
width:14.2857% /* 100/17 */
}
This is optimized for Opera, Chrome, and IE10. Firefox and Safari follow an older Flexbox specification and look best when the lists have a balanced number of items. There's a decent looking fallback for non-Flexbox browsers. You'll likely need to add additional styling to disguise the uneven list heights.

The fact that you have 2 lists where you want to equalize the widths of the elements is what makes Flexbox necessary. If you had only a single list, you could simplify the whole thing down to just using display: table on the ul and display: table-cell on the li.
