How to detect css blur support with Modernizr? - modernizr

How can I detect if browser supports css blur?
Can I use any of these default classes Modernizr puts to html tag?
borderimage borderradius boxshadow textshadow opacity cssanimations csscolumns cssgradients no-cssreflections csstransforms csstransforms3d csstransitions
I'd need to disable all blurs (or enable) css blurs to only supported browsers in css. Thank you

If you go to: https://modernizr.com/download?setclasses, and then select the CSS Filters you will see the following example:
CSS
.no-cssfilters .box { color: red; }
.cssfilters .box { color: green; }
JS
if (Modernizr.cssfilters) {
// supported
} else {
// not-supported
}
I believe that this is what you need.

How to render SCSS while keeping nesting?

I am creating a SCSS -> HTML plugin and need to first render SCSS -> CSS while keeping the nesting so I can then parse with PostCSS to then create an HTML tree with.
I would like to render SCSS like this
// myMixin.scss
#mixin myMixin {
.myMixin {
padding: 1rem;
background: yellow;
}
}
// main.scss
#import 'myMixin.scss';
$blue: #004AAD;
.button {
.text {
color: $blue;
}
#include myMixin;
}
And the output would look like this:
.button {
.text {
color: #004AAD;
}
.myMixin {
padding: 1rem;
background: yellow;
}
}
Basically, I'd like a way to render everything in SCSS while keeping the original nesting. Is it possible? Thanks.
Nesting is specific to SCSS. Also I don't think #import is best practice, use #use instead.
https://sass-lang.com/documentation/at-rules/use
Here is the thing our client(browsers) only support raw CSS and not SCSS, When you use SCSS it compiles down to raw CSS, And CSS doesn't have inbuilt Nesting feature.

How could I show animated svg in some browsers, but static svg or png in firefox?

I have an animated svg, but firefox doesn't currently support the transform-origin property with % for svgs. So I'd like to hide the animated svg and show a static svg or png when users view in firefox. I'm not sure how to do this. I don't think feature detection will work, because firefox does support svgs and transform-origin, just not transform-origin for svg. Thanks for any suggestions.
Had this issue. I remember reading a comment somewhere in SO that Firefox42 supports this with a prefix:
-moz-transform-origin
anyway, to detect firefox i use a snippet found here:
if(navigator.userAgent.toLowerCase().indexOf('firefox') > -1)
{
//Do Firefox-related activities
}
in your case, if the browser is indeed firefox, and assuming you are using 2 container elements, 1 for your SVG and one for your PNG, you could:
1) directly add/show the elements with js
2) add a 'firefox' class to your root html element and style your css accordingly.
so, let's say you have a #svg and #png containers
in your css you'd use:
.firefox #png { display: block; }
#png { display: none; }
#svg { display: block; }
.firefox #svg { display: none; }
Hope this helps!

jqGrid: change background Image in the header of grid

I have a jqGrid and it comes with default background image, I want to change the background image of it. I tried couple of ways as suggested in online
METHOD 1. I added below code in my CSS
.ui-jqgrid .ui-widget-header
{
background-image:url(images/my-header.png) repeat-x !important;
}
METHOD 2.Added below code to load complete event of jqGrid
loadComplete: function () {
$("#gview_jqgCUST .ui-jqgrid-titlebar").removeClass('ui-widget-header');
$("#gview_jqgCUST .ui-jqgrid-titlebar").addClass('jqgrid-header');
}
in CSS I added
.jqgrid-header{
background:red url(images/my-header.png) repeat-x scroll 50% 50%;
border:1px solid black;
color:Blue;
font-weight:bold;
}
and I am loading css files after jqGrid css file but could not achieve it
How can I do it ?? Any sample code please... I am new to jqGrid and jQuery..
First of all you can use ThemeRoller of jQuery UI to customize theme which you use on the page. You can reduce the applying of the theme only to a paer of your page by usage of "CSS Scope" (see the answer).
Alternatively you can specify background of .ui-jqgrid .ui-widget-header. The demo uses the background from "Dot Luv" theme. Additional to background I specified colors of the text and the border to make the look of header better. I used CSS
.ui-jqgrid .ui-widget-header {
border: 1px solid #0b3e6f;
background: #0b3e6f url(http://ajax.aspnetcdn.com/ajax/jquery.ui/1.10.3/themes/dot-luv/images//ui-bg_diagonals-thick_15_0b3e6f_40x40.png) 50% 50% repeat-x;
color: #f6f6f6;
}
The resulting grid looks like on the picture below

How to set active icon colour in Sencha Touch 2.2 Tabpanel app

I've been having difficulty changing the active colour of an icon in my tabpanel item in Sencha Touch 2.2. I've tried lots of variations of CSS and SASS but have not managed to change it. The CSS I have tried:
.x-tabbar.x-docked-bottom .x-tab-active {
color: #000000;
background-color: #000000;
}
.x-tab-active {
background-color: #000000;
color: #000000;
}
I've also tried setting the active colour in SASS, but this doesn't seem to work either. The only bit of CSS that seems to have that blue in it is this bit:
.x-tabbar-light .x-tab-active .x-button-icon::before {
color: #1da2ff;
}
...but when I try setting that to black, nothing happens! Anyone have any ideas how I can change it??
EDIT: I tried the first suggestion changing the CSS to this:
.x-tabbar-light .x-tab-active .x-button-icon {
background-color: #000000;
}
...but this is what I see:
Applying color: #1da2ff; to the :before pseudo-element is the right thing.
The reason why it doesn't work for you is that the rule get overridden by another one with a more specific selector:
.x-tabbar-dark.x-docked-bottom .x-tab-active .x-button-icon:before {
color: #50b7ff;
}
This is the exact situation where using !important is appropriate and not shameful:
.x-button-icon:before {
color: #1da2ff !important;
}
You have the right idea by selecting the icon, which is a span, and not the wrap, which is a div.
The div wrap .x-tab-active has a background color that decides the background of the active box. The icon has an image mask so background color or background-image gradient will determine the color of the icon. There is an additional span that wraps the text, like "x-button-label, for which a color style will change its color.
For changing the color of the icon try:
.x-tabbar-light .x-tab-active .x-button-icon {
background-color: #1da2ff;
}
Thanks a lot, it was enough to add this in my CSS:
.x-tabbar-light.x-docked-bottom .x-tab-active .x-button-icon:before {
color : #000;
}
There was no need to add !important for me as I was using the new base theme for ST 2.2, but your solution worked great!

jqGrid Pager Area - Using Font Awesome Icons

I would like to use Font Awesome icons:
<i class="icon-edit"></i>
in the jqGrid pager area instead of the physical images by default.
.navButtonAdd('#vw_ComplaintSearchGridPager', { caption: '', buttonicon: 'ui-icon-disk', title: 'Save Grid Settings', onClickButton: function () { $(this).SaveGridSetting(); } })
Does anyone know how to achieve this?
It's very interesting question! I never used Font Awesome icons before, but it seems very interesting project.
jqGrid has currently no direct support of Font Awesome icons, but I prepared the simple demo which shows how to replace the standard jQuery UI navigator icons with the corresponding icons from Font Awesome.
One can see mostly clear the difference to the original navigator icons after zoom of the page. I included below the navigator displayed with zoom 400%:
The original navigator using jQuery UI icons
The navigator with Font Awesome icons:
The code which I used is very simple. Instead of usage
$grid.jqGrid("navGrid", "#pager", {view: true});
I used
$grid.jqGrid("navGrid", "#pager", {editicon: "icon-pencil",
addicon: "icon-plus", delicon: "icon-trash", searchicon: "icon-search",
refreshicon: "icon-refresh", viewicon: "icon-file",view: true});
$("#pager .navtable .ui-pg-div>span").removeClass("ui-icon");
I added the CSS
.ui-jqgrid .ui-jqgrid-pager .ui-pg-div>span { margin: 0 5px; font-size: 12px; }
I think it's possible to replace more jQuery UI icons to Font Awesome icons, but it's not very simple. I will think about the problem more and will contact the developer of jqGrid (Tony Tomov) to consider to make jqGrid more friendly to Font Awesome icons, so that it could be possible very simple switch to Font Awesome icons.
UPDATED: I added the code which allows top replace more icons from the pager:
var $pager = $grid.closest(".ui-jqgrid").find(".ui-pg-table");
$pager.find(".ui-pg-button>span.ui-icon-seek-first")
.removeClass("ui-icon ui-icon-seek-first")
.addClass("icon-step-backward");
$pager.find(".ui-pg-button>span.ui-icon-seek-prev")
.removeClass("ui-icon ui-icon-seek-prev")
.addClass("icon-backward");
$pager.find(".ui-pg-button>span.ui-icon-seek-next")
.removeClass("ui-icon ui-icon-seek-next")
.addClass("icon-forward");
$pager.find(".ui-pg-button>span.ui-icon-seek-end")
.removeClass("ui-icon ui-icon-seek-end")
.addClass("icon-step-forward");
As the result one get the following pager:
instead of
UPDATED 2: The code for changing minimizing icon looks a little completer. One should first change the icon initially
$grid.closest(".ui-jqgrid")
.find(".ui-jqgrid-titlebar>.ui-jqgrid-titlebar-close>.ui-icon-circle-triangle-n")
.removeClass("ui-icon ui-icon-circle-triangle-n")
.addClass("icon-circle-arrow-down");
and then change it after every click on the icon:
onHeaderClick: function (gridstate) {
if (gridstate === "visible") {
$(this.grid.cDiv).find(">.ui-jqgrid-titlebar-close>span")
.removeClass("icon-circle-arrow-up ui-icon-circle-triangle-n")
.addClass("icon-circle-arrow-down");
} else if (gridstate === "hidden") {
$(this.grid.cDiv).find(">.ui-jqgrid-titlebar-close>span")
.removeClass("icon-circle-arrow-down ui-icon-circle-triangle-s")
.addClass("icon-circle-arrow-up");
}
}
Additionally one need to add the CSS
.ui-jqgrid .ui-jqgrid-titlebar-close>span { margin: 0 3px; font-size: 16px; }
.ui-jqgrid .ui-jqgrid-titlebar-close { text-decoration: none; }
To fix the sorting icons I used the code
var $sortables = $grid.closest(".ui-jqgrid")
.find(".ui-jqgrid-htable .ui-jqgrid-labels .ui-jqgrid-sortable span.s-ico");
$sortables.find(">span.ui-icon-triangle-1-s")
.removeClass("ui-icon ui-icon-triangle-1-s")
.addClass("icon-sort-down");
$sortables.find(">span.ui-icon-triangle-1-n")
.removeClass("ui-icon ui-icon-triangle-1-n")
.addClass("icon-sort-up");
and the CSS
.ui-jqgrid .ui-icon-asc { height: auto; margin-top: 0; }
.ui-jqgrid .ui-icon-asc, .ui-jqgrid .ui-icon-desc {
height: auto; margin-top: 0; margin-left: 5px;
}
.ui-jqgrid .s-ico>.ui-state-disabled, .s-ico>.ui-state-disabled { padding: 0; }
As the result one will get the following:
UPDATED 3: In the next demo one can find more full replacement of jQuery UI icons to Font Awesome icons.
UPDATED 4: The answer provides solution for Font Awesome version 4.x.
Figured I would put a CSS alternative answer for those interested. One of our developers implemented a JS option, which did functionally work, however, there was a delay before it rendered correctly (not ideal).
We used font-awesome icons for our paging options, and here is how we implemented it.
Found the four classes that jqGrid was using for the paging icons we desired to customize and created the following css to apply base font awesome styles
.ui-icon-seek-next, .ui-icon-seek-prev, .ui-icon-seek-end, .ui-icon-seek-first
{
display: inline-block;
font-family: FontAwesome;
font-style: normal;
font-weight: normal;
line-height: 1;
-webkit-font-smoothing: antialiased;
}
Then it is simply a matter of grabbing the content from font-family icon and using them as your own.
.ui-icon-seek-next:before
{
content: "\f105";
}
.ui-icon-seek-prev:before
{
content: "\f104";
}
.ui-icon-seek-end:before
{
content: "\f101";
}
.ui-icon-seek-first:before
{
content: "\f100";
}
So the entire CSS together looks like this
.ui-icon-seek-next, .ui-icon-seek-prev, .ui-icon-seek-end, .ui-icon-seek-first
{
display: inline-block;
font-family: FontAwesome;
font-style: normal;
font-weight: normal;
line-height: 1;
-webkit-font-smoothing: antialiased;
}
.ui-icon-seek-next:before
{
content: "\f105";
}
.ui-icon-seek-prev:before
{
content: "\f104";
}
.ui-icon-seek-end:before
{
content: "\f101";
}
.ui-icon-seek-first:before
{
content: "\f100";
}
And the output on our grid without JS and without delay
By looking at answer from Oleg above, I did the following to simplify things.
Additional CSS
.ui-jqgrid .ui-jqgrid-pager .ui-pg-div>span.fntawsm { margin: 0 5px; font-size: 12px; padding-left:2px;padding-right:2px;}
** padding-left:2px;padding-right:2px; is optional
And this only works with icons only with no caption ...
And then just start adding fontawesome icons in navButtonAdd like
caption:"", // important for above
title:"Give any",
buttonicon:"fntawsm icon-remove"
buttonicon:"fntawsm icon-eject icon-rotate-90"
etc .. You can use all extra functionality from font-awesome like icon-rotate-XX too.
Thisway i did`nt have to remove ui-icon class from spans.
Inspired by #afreeland answer, I created a css available on github which allows you to convert your icons to Font-Awesome icons.
The performance advantage of this over the jquery method that #Oleg described is important in my opinion.
It is also a very elegant solution in my opinion.
You are welcome to use it: https://github.com/guylando/ToAF
Note: you must give priority for this ToAF.css file styles over your other icons styles so that can be achieved for example by copying the css content into a tag in your document.
