How do add better responsive queries in SASS? - css

What is the better SASS way to write the code below. I end up writing lots of media queries with dimensions and also repeating classes in SASS - surely there is a nice way to use mixins or includes? Anyone else write media queries better than below?
$strFullWidth:100%;
.aboutWrapper {
.logo{width:$strFullWidth;max-width:620px}
}
// MOBILE
#media only screen and (max-width:850px){
.aboutWrapper {
.logo{width:$strFullWidth;max-width:420px}
}
}
// SMALL MOBILE
#media only screen and (max-width:550px){
.aboutWrapper {
.logo{width:$strFullWidth;max-width:320px}
}
}

I like the queries David Walsh proposes in his blog post. So in your case the mixins could look like:
#mixin mobile {
#media only screen and (max-width:850px) {
#content;
}
}
#mixin smallMobile {
#media only screen and (max-width:550px) {
#content;
}
}
With these mixings, your SCSS code boils down to:
$strFullWidth:100%;
.aboutWrapper {
.logo {
width:$strFullWidth;
max-width:620px;
}
}
#include mobile {
.aboutWrapper .logo { max-width:420px; }
}
#include smallMobile {
.aboutWrapper .logo { max-width:320px; }
}

SCSS breakpoints in custom WordPress theme not working as intended

So I I am trying to style a custom wordpress theme, however the breakpoints I'm using are being applied at all screen sizes, literally just overwriting the styles I've already written. I have never had this problem before, and I have used this exact code on other, non-WordPress sites. In fact I literally copied it over from a site I made in Gatsby.
this is my _breakpoints.scss file
$breakpoints: (
"xs":0,
"sm":30rem,
"md":45rem,
"lg":60rem,
"xl":75rem,
);
#mixin xs {
#media (min-width: map-get($breakpoints, "xs")){
#content;
}
}
#mixin sm {
#media (min-width: map-get($breakpoints, "sm")){
#content;
}
}
#mixin md {
#media (min-width: map-get($breakpoints, "md")){
#content;
}
}
#mixin lg {
#media (min-width: map-get($breakpoints, "lg")){
#content;
}
}
#mixin xl {
#media (min-width: map-get($breakpoints, "xl")){
#content;
}
}
#mixin breakpoint($bp: 0) {
#media (min-width: $bp) {
#content;
}
}
and this is the element I am working on. the element should be hidden until the lg breakpoint (60rem/960px)
.hero-logo-container {
display: none;
#include lg {
display: block;
}
}
I did wonder was it something odd with flexbox, but like I said I've literally just used the exact same _breakpoints .scss on another site and it works fine. I have also thought that this may be some odd quirk of WordPress?
any help you can give me would be appreciated
I have tried hard-coding the file path to the image, in case that was the culprit (rather than using get_theme_file_uri()) but that wasn't it, other styles are just being similarly overridden.
I have recreated what has been built so far in basic HTML, with the same SCSS files and the problem is happening there.
I just can't see what I'm doing wrong...

How can SASS help me develop responsive web designs?

I have been designing with CSS for years, but I am only just now learning how to use SASS. This is very much a beginner question, so please bear with me.
The reason I started looking into SASS was because I wanted to develop a responsive web design, but was hoping there was a better way to do it than manually make different style sheets for every screen size.
I believe that in principle, a CSS preprossesor like SASS should help with this issue... but at the moment I don't understand how.
If I have a div with the id #squishable, and on large screens I want it to have a width of 1000 pixels, and on small screens a width of 100 pixels, but a red background in both cases, I think I would do something like this:
$color = red;
#squishable {
backgorundcolor: $color;
}
#media only screen
and (min-width : 321px) {
#squishable {
width:100px;
}
}
#media only screen
and (min-width : 1824px) {
#squishable {
width:1000px;
}
}
However, I'm not sure this approach is in much of an advantage over just using CSS. Maybe as an example, it's too simplistic. But, in any case, I don't see exactly what I would be doing differently with SASS to make it easier to code for a responsive web design. Is this all there is to it?
Can someone help me get over this conceptual hurdle and let me know how I take advantage of SASS to create elements that are responsive? Hopefully with a simple example similar to what I've got above?
You can absolutely improve your workflow further!
Using SASS #mixin, #include, #content and regular variables you can setup an environment where you create your media queries "inline", or inside of your regular selectors if you will.
This is my mixin for media queries:
(never mind the stupid variable names and placeholder breakpoints)
// Breakpoints
$mq-tiny: 5em;
$mq-small: 10em;
$mq-medium: 15em;
$mq-large: 20em;
$mq-huge: 25em;
$mq-crazy: 30em;
#mixin mq($size, $direction: min-width, $media-type: only all) {
#if $size == tiny { #media #{$media-type} and (#{$direction}: $mq-tiny) { #content; } }
#else if $size == small { #media #{$media-type} and (#{$direction}: $mq-small) { #content; } }
#else if $size == medium { #media #{$media-type} and (#{$direction}: $mq-medium) { #content; } }
#else if $size == large { #media #{$media-type} and (#{$direction}: $mq-large) { #content; } }
#else if $size == huge { #media #{$media-type} and (#{$direction}: $mq-huge) { #content; } }
#else if $size == crazy { #media #{$media-type} and (#{$direction}: $mq-crazy) { #content; } }
#else { #media #{$media-type} and (#{$direction}: $size) { #content; } }
}
And here's an example of how it can be used:
SCSS:
.selector {
width: 100px;
#include mq(large) {
width: 1000px;
}
}
CSS output:
.selector {
width: 100px
}
#media only all and (min-width: 20em) {
.selector {
width: 1000px
}
}
Take note that you don't need to use a variable name for the width. You can pass 1000px instead of large if you want to.
You may also have noticed the optional arguments in the #mixin; $direction and $media-type. These arguments default to min-width and only all respectively, but if you pass them through the #include they'll change for that specific element only.
Example with other arguments:
SCSS:
.selector {
#include mq(1000px, min-height) {
width: 100px;
}
}
CSS output:
#media only all and (min-height: 1000px) {
.selector {
width: 100px
}
}
Hope this helps!
Edit:
Here's a pen if you want to play around with it.
To increase maintainability of your code you can use variables to define media queries breakpoints:
// define breakpoints
$small-screen: 321px;
$large-screen: 1824px;
$small: "only screen and (min-width:"#{$small-screen}")";
$large: "only screen and (min-width:"#{$large-screen}")";
// and so on...
// now you can esely manipulate with your media breakpoints
#media #{$small} {
...
}
#media #{$large} {
...
}
Highly recommend you develop your SAAS css style import bootstrap framework, it will save you much time at responsive web designs

Media queries with Sass won't compile

I'm getting errors compiling my Sass files using media query mixins. I followed several tutorials, but it won't compile. I'm using Sass 3.3.0.alpha.67 (Bleeding Edge).
Here's my code
/* Included at the end */
#mixin mobile-only {
#media (max-width : 320px) {
#content;
}
}
/* Included where the rest of my sass is */
body { #include mobile-only {
display: none;
}
}
I'm using Scout to compile and watch for changes. Is there anything else I need to be doing?
Doesn't seem to be an issue anymore. The slightly modified code is explained in this codepen http://codepen.io/danielcgold/pen/RRNrPQ.
#mixin start-desktop-size {
#media (min-width: 1024px) {
#content;
}
}
body {
#include start-desktop-size {
background: red;
}
}

Media Queries with SCSS not applying

I'm trying to test the following code out in Chrome and Firefox and neither is picking it up. I have added it to the end of my stylesheet which works fine anyway.
#media all and (max-width : 850px) {
h1#site-name {
width: 100%;
a {
margin: auto;
}
}
nav#main-menu {
float: left;
}
}
I am re-sizing my browser window and the changes are obviously not taking effect at any width. The code is within a .scss file for reference.
Any ideas?
You can use mixins for media queries in scss too.
#mixin mq($mq) {
#if $mq == medium {
#media (max-width: 850px) { #content; }
}
}
#main-menu {
// default styles
// media query 850px max-width
#include mq(medium) {
float: left;
}
}

Handling custom media queries in Sass with Twitter Bootstrap

I have a Sass mixin for my media queries based on Twitter Bootstrap's responsive media queries:
#mixin respond-to($media) {
#if $media == handhelds {
/* Landscape phones and down */
#media (max-width: 480px) { #content; }
}
#else if $media == small {
/* Landscape phone to portrait tablet */
#media (max-width: 767px) {#content; }
}
#else if $media == medium {
/* Portrait tablet to landscape and desktop */
#media (min-width: 768px) and (max-width: 979px) { #content; }
}
#else if $media == large {
/* Large desktop */
#media (min-width: 1200px) { #content; }
}
#else {
#media only screen and (max-width: #{$media}px) { #content; }
}
}
And I call them throughout my SCSS file like so:
.link {
color:blue;
#include respond-to(medium) {
color: red;
}
}
However, sometimes I want to style multiple queries with the same styles. Right now I'm doing them like this:
.link {
color:blue; /* this is fine for handheld and small sizes*/
/*now I want to change the styles that are cascading to medium and large*/
#include respond-to(medium) {
color: red;
}
#include respond-to(large) {
color: red;
}
}
but I'm repeating code so I'm wondering if there is a more concise way to write it so I can target multiple queries. Something like this so I don't need to repeat my code (I know this doesn't work):
#include respond-to(medium, large) {
color: red;
}
Any suggestions on the best way to handle this?
A mixin like that leaves you in a position that's not very flexible, and not just because you're using px (see: http://blog.cloudfour.com/the-ems-have-it-proportional-media-queries-ftw/). Simply put, you've made your mixin too specific and not very reusable for other sites.
I'm currently using a collection of 4 mixins to handle the most common media queries: min-width, max-width, between, and outside (I've sampled min-width and between below)
$output-media-width: true !default; // true = all, otherwise use a list of numeric values (eg. 320px 23em)
#mixin media-min-width($bp) {
#if type-of($output-media-width) != list {
#media (min-width: $bp) {
#content;
}
} #else {
$output-bp: find-comparable($bp, $output-media-width);
#if not comparable($output-bp, $bp) {
#debug "Output breakpoint: #{$output-bp}, Chosen minimum width: #{$bp}";
} #else if $output-bp >= $bp {
#content;
}
}
}
#mixin media-between($bp1, $bp2) {
#if type-of($output-media-width) != list {
#media (min-width: $bp1) and (max-width: make-less-than($bp2)) {
#content;
}
} #else {
$output-bp1: find-comparable($bp1, $output-media-width);
$output-bp2: find-comparable($bp2, $output-media-width);
#if not comparable($output-bp1, $bp1) or not comparable($output-bp2, $bp2) {
#debug "Output breakpoints: #{$output-bp1} and #{$output-bp2}, Chosen breakpoints: #{$bp1} and #{$bp2}";
} #else if $output-bp2 >= $bp1 and $output-bp2 < $bp2 {
#content;
}
}
}
#function find-comparable($val, $list) {
#each $item in $list {
#if comparable($val, $item) {
#return $item;
}
}
}
#function make-less-than($val) {
#return if(unit($val) == em, $val - .001, $val - 1);
}
This mixin suite lets me generate a responsive CSS file or a collection of non-responsive CSS files at any width I desire (specifically for devices that don't take kindly to media queries) just by having a variable like this at the top of my file:
$output-media-width: 800px 60em;
A list of sizes lets me use px in those rare cases where em is inappropriate (such as for dealing with images).
// Device widths
$device-x-narrow: 23em; // 320px
$device-narrow: 35em; // 480px
$device-medium: 60em; // 800px
$device-wide: 70em; // 1000px
article.event {
#mixin tableify {
// footer { display: table-row }
footer section { display: table-cell }
footer section + section { padding-left: 2em }
}
#include media-min-width($device-medium) { // 2-col layout still
#main > & { // single event view
#include tableify;
}
}
// sometimes you need a non-standard breakpoint, too...
#include media-min-width(27em) { // narrow devices
section & {
#include tableify;
}
}
#include media-max-width(27em) {
footer section.categories ul {
display: block;
padding-left: 0;
li { display: inline }
li + li { margin-left: 1em }
}
}
}
Despite the fact that #cimmanon answered my question before I posted that I was using Twitter Bootstrap, it had some really interesting ideas in it which I think I'll apply from now on for my Sass projects that use Twitter Bootstrap. Here is what I found worked great:
/* Responsive dimensions */
$handheld-max: 479px;
$small-min: $handheld-max + 1;
$small-max: 767px;
$medium-min: $small-max + 1;
$medium-max: 979px;
$large-min: $medium-max + 1;
$large-max: 1199px;
$xlarge: 1200;
/*Responsive query mixins */
#mixin media-above($min) {
#media (min-width: $min) { #content; }
}
#mixin media-below($max) {
#media (max-width: $max) { #content; }
}
#mixin media-between($min, $max) {
#media (min-width: $min) and (max-width: $max) { #content; }
}
and then call it in my code like so (based on my request in the question):
.link {
color: blue;
#mixin media-above($medium-min){
color: red;
}
}
Using bootstrap-sass variables, I defined such mixins in SASS syntax:
=media-width-below($max)
#media (max-width: $max)
#content
=media-width-between($min, $max)
#media (min-width: $min), (max-width: $max)
#content
=media-width-above($min)
#media (min-width: $min)
#content
=media-xs
+media-width-above($screen-xs-min)
#content
=media-sm
+media-width-above($screen-sm-min)
#content
=media-md
+media-width-above($screen-md-min)
#content
=media-lg
+media-width-above($screen-lg-min)
#content
Those mixins will be useable just like +make-sm-column or .col-md-5 classes. You can just use it like this:
body
+media-xs
background-color: yellow
+media-sm
background-color: blue
+media-md
background-color: red
+media-lg
background-color: green
When you will be making your browser smaller by changing it from large to xs, you'll see colors in this order: green, red, blue, yellow.
