Decrease Font Size When Viewing on Small Screens With Tailwindcss - tailwind-css

I want to keep base font size at 1rem, and when user views on mobile (under 640px) change it to .75rem (TW .text-sm class)
I thought doing it this way would work but seems like it's producing the opposite effect:
<p class="text-base sm:text-xs">Some paragraph text</p>
Codepen example here

Figured it out. Since TW is mobile first, I had to define my base size, then target the rest:
<p class="text-xs sm:text-base">Some paragraph text</p>

How to set the div and its children to responsive mode without using an iframe in TailwindCSS?

I'm creating a page where I have a parent div which encapsulates multiple child divs from different components in a NextJs project.
I have a preview option where my customers can preview their changes in mobile and desktop view.
I'm able to switch to mobile view using iframe. I want to achieve this without using an iframe.
Even though I change the parent div max width, because the rest of components have sm md lg xl which are taking the values from the view port instead of the parent div I'm unable to solve it.
What should be the approach to solve this?
The simplest way to access children in Tailwindcss is to class [&>] to the parent div. For example, let's say you have 5 child divs. If you want to give an attribute to the last of them [&>div:last-child]:bg-blue-500 , if you want to make it responsive, max-md:[&>div:last-child]:bg-blue-500 you have to express. I have prepared a demo for you to make it more meaningful, you can check it from the link below. If you expand the preview screen on the right a little, you will see that the colors have disappeared. I hope it can solve your problem.
Demo Code
Not sure what you meant complelty
<div class="max-w-full sm:max-w-full md:max-w-3xl lg:max-w-4xl xl:max-w-5xl">
<div class="text-sm sm:text-base md:text-lg lg:text-xl xl:text-2xl">
For small screen sizes
</div>
<div class="flex-sm-row sm:flex-row md:flex-col lg:flex-col xl:flex-col">
<div class="w-sm sm:w-1/2 md:w-1/3 lg:w-1/4 xl:w-1/5">
This for 50% width
</div>
<div class="w-sm sm:w-1/2 md:w-1/3 lg:w-1/4 xl:w-1/5">
This for 50% width
</div>
</div>
<div class="hidden sm:hidden md:block lg:block xl:block">
For large and extra-large screen sizes.
</div>
</div>
Media breakpoints allows you to change content appearance based on viewport size. Tailwind's media variants like md:, lg: etc based on them. In order to change content based on parent's size you should use CSS Container Queries. Be aware - they are not production ready - about 75% browser support (actual at December 2022)
Container queries allow us to look at a container size and apply styles to the contents based on the size of their container rather than the viewport or other device characteristics.
Tailwind has official plugin which may help you with it. Install it configure within tailwind.config.js
module.exports = {
plugins: [
require('#tailwindcss/container-queries'),
],
}
You need to add #container class to a parent container and use size modifiers on element you need like #md:bg-blue-500.
<div class="#container max-w-full resize-x overflow-auto">
<div class="p-16 #md:bg-blue-500 bg-amber-400">
Resize me
</div>
</div>
This way element should be yellow unless container size is bigger than 28rem and it will become blue no matter viewport size
Produced CSS is
#container (min-width: 28rem) {
.\#md\:bg-blue-500 {
--tw-bg-opacity: 1;
background-color: rgb(59 130 246 / var(--tw-bg-opacity));
}
}
Check other modifiers here. Please note md:flex and #md:flex are different sizes which may confuse at first
#containers supports labels so you can name containers and specify different CSS for them. Let's say you have reusable component (common situation) you include within loop
<div class="#4xl/aside:bg-red-500 #3xl/primary:bg-yellow-500">
</div>
So within #container/aside element your card will be red after #4xl (56rem) size, while within #container/primary - yellow after #3xl (48rem).
<div class="#container/aside">
<div class="#4xl/aside:bg-red-500 #3xl/primary:bg-yellow-500">
YELLOW
</div>
</div>
<div class="#container/aside">
<div class="#4xl/aside:bg-red-500 #3xl/primary:bg-yellow-500">
RED
</div>
</div>
As I said it's not production ready. The way you want to handle unsupported browsers is up to you. First one - use polyfill. Just add
<script src="https://cdn.jsdelivr.net/npm/container-query-polyfill#1/dist/container-query-polyfill.modern.js"></script>
and it should be enough. However read full docs to improve user experience. I didn't fully tested it myself so cannot guarantee it is 100% solution
Second way is to check does browser supports container queries or not. You can check it via JS
if (!("container" in document.documentElement.style)) {
console.log('No support')
// Do something in that case
}
Another way - via CSS #supports rule
#supports (container-type:inline-size) {
/** Container queries supported */
}
Tailwind has supports: variant for that needs so something like this would work
<div class="supports-[container-type:inline-size]:hidden">
Your browser does not support container queries
Maybe show iframe element as backup (?)
</div>
<div class="supports-[container-type:inline-size]:block hidden">
Here is my cool feature which will be hidden if browser does not supports container queries
</div>
I've created this demo playground without polyfill to check different cases depends on container and window size plus different types of container and browser support
A solution to this can be adding a w-screen to parent div.
Use w-screen to make an element span the entire width of the viewport.

Unexpected font size of textarea using rem in Chrome when setting root element font size to percentage

When setting the root font-size to 62.5% or any other percentage, Chrome renders the textarea font size as 16.25px. I expected it to be 20px just like the div font size is being rendered. Also, in Firefox, both the div and textarea are rendering at 20px. I'm a bit confused as to why this would be in Chrome. Shouldn't the rem value be consistently based on the root element?
Note that setting the root element font-size to a fixed pixel amount, things work as expected.
By the way, I'm on Windows 10 and am unsure if this happens on Mac. Also, I suppose I can switch to using pixels, however I was hoping to use the percentage based size so I can keep the user font size preference.
<html style="font-size: 62.5%">
<body>
<div style="font-size: 2rem">asdf</div>
<textarea style="font-size: 2rem">asdf</textarea>
</body>
</html>
Update:
When I change the font family on the root to anything other than monospace it seems to work find. Only with monospace this issue occurs. Still stumped on why this is happening...
<html style="font-size: 62.5%">
<body>
<div style="font-size: 2rem">asdf</div>
<textarea style="font-size: 2rem; font-family: sans-serif">asdf</textarea> <!-- 20px -->
</body>
</html>
You are using percentage so its not specific like pixels, So its normal if you see different values of size's in different browsers.
i suggest you use a font base and use rem or % on that and try to use pixels and media query for responsive...

Pure css grid problem when changing the chrome screen size to mobile size

I try to use pure css grid system like explained in the documentation but I'm not able to make it work on desktop resolution and mobile like Pixel 2 resolution.
Instead of going on 2 lines like this :
I got this letter-spacing problem and the div goes on the same line :
Like to code example
<div class="pure-g">
<div class="pure-u-sm-1-1 pure-u-md-1-1 pure-u-lg-9-24">
<div class="l-box">
<span class="fa-stack">
<i class="fa fa-circle fa-stack-1And5x"></i>
<strong class="fa-stack-1x label-white">4</strong>
</span>
<label>Test:</label>
</div>
</div>
<div class="pure-u-sm-1-1 pure-u-md-1-1 pure-u-lg-15-24">
<div class="l-box">
<input class="pure-radio" id="montant" name="montant" type="text" value="">
</div>
</div>
</div>
There is a problem with your grid system and your media queries.
sm specifies the behavior only for screen sizes with a width of at least 568px. Below that your problem occurs.
To solve this add the pure-u-1-1 class respectively - you could say it defines your standard behavior. This alone won't work though because you make use of another stylesheet for normalizing your CSS. Put your normalizing CSS file in front of the other stylesheet in your code, otherwise it overrides some of your other CSS rules (keyword cascading style sheet). Always mention your normalizing CSS files first!
Also in this case the pure-u-md-1-1 class seems obsolete because it does not specify another behavior than pure-u-sm-1-1. The latter already defines the same behavior for all screen sizes of at least 568px.

How do I make an icon disappear on mobile?

Hopefully this is a simple answer. I have a page that on desktop needs a series of share icons (fb, tw, ig) underneath a paragraph of text. But on mobile, these icons are included in a template already so I don't need them to show. It looks repetitive. I am using a CMS and only have access to the body text of the page, not the headers, so extensive javascript isn't ideal. What inline CSS styling or other such magic will make this div disappear? And can I shrink it only on verified mobile devices or is it better to do it just with the browser window size?
Currently the code is very simple:
<html>
<body>
Some text here.
<div id="mydiv">
<img src="/some/icon1.png">
<img src="/some/icon2.png">
<img src="/some/icon3.png">
</div>
</body>
</html>
All I need to do is make "mydiv" disappear if I'm using an iPhone, iPad, or Android device...
Thank you!
You can use media queries:
A media query consists of a media type and zero or more expressions that limit the style sheets' scope by using media features, such as width, height, and color.
When a media query is true, the corresponding style sheet or style rules are applied, following the normal cascading rules.
Documentation:
MDN
w3schools
For example:
#media (max-width: 787px) {
#mydiv {
display: none;
}
}
Some text here.
<div id="mydiv">
<img src="/some/icon1.png">
<img src="/some/icon2.png">
<img src="/some/icon3.png">
</div>

Responsive alignment in bootstrap

I want to have 2 buttons groups in one row like this:
[a|b|c] [d|e|f|g|h]
Currently the right button group is a pull-right bootstrap class. Works fine.
But this looks horrible on xs devices - since it's in a new row but still pulled to the right, like this:
[a|b|c]
[d|e|f|g|h]
So what I basically want to do is to combine pull- classes.
pull-right pull-left-xs
Well this example don't work. Is there something similiar? Otherwise: how can I align my content right on md and xl devices and left on all other devices?
Twitter bootstrap has helper classes that could work for what you are trying to do, try with offset .pull and .push classes, something like col-md-push-3 will push your 3 columns only for .md and .lg classes, if you want a different behavior on mobile just reset it to col-xs-push-0.
Check this link for reference http://getbootstrap.com/css/#grid-column-ordering
Why do you need a pull-right. Can't you get the same effect using offset. http://getbootstrap.com/css/#grid-offsetting
So for example you could have
<div class="row">
<div class="col-sm-3 col-xs-4">[a|b|c]</div>
<div class="col-sm-5 col-sm-offset-4 col-xs-8">[d|e|f|g|h]</div>
</div>
For sm screens it will have the offset spacing in between, then for xs it will put it next to each other.
You could use media query and custom class like this..
#media (min-width: 992px) {
.pull-right-sm {
float: right;
}
}
http://bootply.com/i145F3q1Ji
I would steer clear of modifying Bootstrap classes because it will potentially affect other parts of the site where you need the styles to work as originally intended. You will likely also be creating a maintainability challenge for yourself or others in the future. Furthermore, the push and offset does not right align, so it would only get close to what you want.
Bootstrap 4 includes responsive classes that use the same breakpoints as the grid system (e.g. .text-sm-right, .text-md-left etc) that can be used in conjunction with one another as a solution to this. https://v4-alpha.getbootstrap.com/utilities/typography/#text-alignment
Old post but as it was the top answer in google for my search...
Using Bootstrap v4 you can use the float-* classes.
<div class="row">
<div class="col-md-6">
Always left aligned
</div>
<div class="col-md-6 float-md-right">
Right aligned for medium+, left aligned otherwise
</div>
</div>
