How can I add css to be only read by safari? bascially a div needs moving 5pixels to the left, as it shows fine on ff/ie etc
Thanks
EDIT - added code
code:
#subheading
{
background-color: #004376;
color: #ffffff;
height: 25px;
padding: 10px;
margin: 0 933px;
margin-top: -25px;
width: 761px;
}
you can have a check for a specific css property in webkit. This would likely work in chrome as well.
#media screen and (-webkit-min-device-pixel-ratio:0) {
.someClass{
color:#FF0000;
}
}
margin: 0 933px;
margin-top: -25px;
width: 761px;
This doesn't sound right. The first line sets both left and right margin to 933px. And the width is 761px. The total width of the element would be (933 * 2 + 10 * 2 + 761) = 2647px.
Is this what you want it to be?

I have a documentation for my app in readthedocs website. And I have a .css file that changes side bar appearance. About three month ago this .css file worked well, but now it doesn't. Here is the link.
That is how it looked like:
That is how it looks now:
The .css file:
/* Fixes the size of the RTD flyout */
/* .rst-versions {
width: 320px !important;
} */
/* Content area color */
.wy-nav-content {
background: #dddddd;
}
/* Scroll Bar*/
.wy-side-scroll {
width: auto;
overflow-y: auto;
margin-top: 0px;
}
/* width of the side panel */
.wy-nav-side {
width: 320px;
}
/* content section full screen */
.wy-nav-content {
max-width: none;
}
/* set color of left side bar */
.wy-nav-side,.wy-side-nav-search,.wy-nav-top {
/*background: #0079c1; /*005eb8 */
background: #006464;
}
/* Change caption color to be more legible */
.wy-menu > .caption > span.caption-text {
color: #ffcccc;
font-size: 20px;
}
/* Change the version color to match caption color */
.wy-side-nav-search>div.version {
color: #ffcccc;
}
/* Get rid of that ugly yellow highlight color and replace with something more appealing to the eye */
.highlight .hll {
background-color: #fcfcfc;
}
/*
#media screen and (max-width: 768px) {
.wy-nav-content-wrap {
margin-left: 0px;
}
.wy-nav-side {
width: 500px;
}
} */
What could be the reason of this? Thanks!
I partially confirm what #Steve Piercy says in the comment. The rule .wy-menu > .caption > span.caption-text { doesn't work anymore, since the <p> that surrounds the <span class="caption-text"> no longer has a caption class. You can check that by comparing latest with 1.3.4-branch.
However, as you can see from the build logs (old, new), the problem is not with sphinx-rtd-theme (you are using 0.5.0 in both), but the docutils version (0.16 in the old build, 0.17 in the new build). You will need to either upgrade your Sphinx version, or downgrade docutils.
I would like to use ::before to place SVG images before some selected elements:
#mydiv::before {
content: '<svg ... code here</svg>';
display: block;
width: 22px;
height: 10px;
margin: 10px 5px 0 10px;
}
Above code just displays the plaintext.
I checked the spec and there seem to be some restrictions on what content can be. CSS content property solution is preferable.
Yes you can! Just tested this and it works great, this is awesome!
#test::before {
content: url(path/to/your.svg);
width: 200px;
height: 200px;
}
Or if you prefer to put the SVG directly in the CSS:
#test::before {
content: url("data:image/svg+xml,%3Csvg xmlns='http://www.w3.org/2000/svg'%3E%3Ccircle cx='100' cy='50' r='40' stroke='black' stroke-width='2' fill='red'/%3E%3Cpolyline points='20,20 40,25 60,40 80,120 120,140 200,180' style='fill:none;stroke:black;stroke-width:3'/%3E%3C/svg%3E ");
width: 200px;
height: 200px;
}
<div id="test"></div>
SVG URL encoder to format your own SVGs as shown here.
You can use the url() CSS function.
#mydiv::before {
content: url("data:image/svg+xml; utf8, <svg ... code here</svg>");
display: block;
width: 22px;
height: 10px;
margin: 10px 5px 0 10px;
}
Make sure your SVG doesn't contain any # symbols. Use an encoder like this one.
You can add the SVG as background-image of an empty :after or :before.
Here you go:
.anchor:before {
display: block;
content: ' ';
background-image: url('../images/anchor.svg');
background-size: 28px 28px;
height: 28px;
width: 28px;

Convenient tool for SVG encoding url-encoder
Making use of CSS sprites and data uri gives extra interesting benefits like fast loading and less requests AND we get IE8 support by using image/base64:
Codepen sample using SVG
HTML
<div class="div1"></div>
<div class="div2"></div>
CSS
.div1:after, .div2:after {
content: '';
display: block;
height: 80px;
width: 80px;
background-image: url(data:image/svg+xml,%3Csvg%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%20version%3D%221.1%22%20height%3D%2280%22%20width%3D%22160%22%3E%0D%0A%20%20%3Ccircle%20cx%3D%2240%22%20cy%3D%2240%22%20r%3D%2238%22%20stroke%3D%22black%22%20stroke-width%3D%221%22%20fill%3D%22red%22%20%2F%3E%0D%0A%20%20%3Ccircle%20cx%3D%22120%22%20cy%3D%2240%22%20r%3D%2238%22%20stroke%3D%22black%22%20stroke-width%3D%221%22%20fill%3D%22blue%22%20%2F%3E%0D%0A%3C%2Fsvg%3E);
}
.div2:after {
background-position: -80px 0;
}
For IE8, change to this:
background-image: url(data:image/png;base64,data......);
To extend further this topic. In case you want to add Font Awesome 5 icons you need to add some extra CSS.
Icons by default have classes svg-inline--fa and fa-w-*.
There are also modifier classes like fa-lg, fa-rotate-* and other. You need to check svg-with-js.css file and find proper CSS for that.
You need to add your own color to css icon otherwise it will be black by default, for example fill='%23f00' where %23 is encoded #.
h1::before{
/* svg-inline--fa */
display:inline-block;
font-size:inherit;
height:1em;
overflow:visible;
vertical-align:-.125em;
/* fa-w-14 */
width:.875em;

<h1>Lorem Ipsum</h1>
Be careful all of the other answers have some problem in IE.
Lets have this situation - button with prepended icon. All browsers handles this correctly, but IE takes the width of the element and scales the before content to fit it. JSFiddle
#mydiv1 { width: 200px; height: 30px; background: green; }
#mydiv1:before {
content: url("data:url or /standard/url.svg");
}
Solution is to set size to before element and leave it where it is:
#mydiv2 { width: 200px; height: 30px; background: green; }
#mydiv2:before {
content: url("data:url or /standard/url.svg");
display: inline-block;
width: 16px; //only one size is alright, IE scales uniformly to fit it
}
The background-image + background-size solutions works as well, but is little unhandy, since you have to specify the same sizes twice.
The result in IE11:
Although this was many years ago, I'd like to also share this.
The answers above are correct, you can directly attach the encoded svg string into the css content property. For those having any issues with the URL it may be due to spaces and characters not valid for such, in that case paste your decoded SVG code into:
https://mothereff.in/url
Use the encoded SVG URL and it should work fine.

I just today noticed that a newspaper here used direct injection of the SVG into the ::before and ::after pseudo-elements to render stylized quotes for highlighted content in the article. I tried to find that paper's CMS via whatcms.org but to no avail. I can say however that the owner newspaper - a large national, even international, paper uses a CMS called DM Polopoly.
It seems so much more laborious to enter SVG data into the content element rather than blank the content and use the SVG as a background image. I wonder why they chose this method - what advantage went with this. I've seen some people on Google links who said it made it easy to manipulate the SVG image on hovering upon the pseudo-element . . . But I saw no killer example of this 'benefit'.
This article has a simpler method for inserting the SVG as content.
It uses a zoom property to get size adjustment for the image.
using a background mask image with empty content, you can control the color from within css: (Don't forget the position, width and height that you prefer)...!
background-color: red;
-webkit-mask-image: url(icon.svg);
mask-image: url(icon.svg);
content:'';
.myDiv {
display: flex;
align-items: center;
}
.myDiv:before {
display: inline-block;
content: url(./dog.svg);
margin-right: 15px;
width: 10px;
}
I am using ui-grid. I have a lot of rows and that is why I use scrolling. Everything works perfectly ok until I try to change the height of the rows. Then the scrolling becomes a mess. I have added an example here http://plnkr.co/edit/S6ylwOVgcQp7CSsZZxpR?p=preview
This is one of the tutorials from the ui-grid website - the only thing I have changed is the CSS. I have added these rules.
.ui-grid-cell-contents {
padding: 1px 1px;
}
.ui-grid-render-container-body .ui-grid-header-cell,
.ui-grid-render-container-left .ui-grid-header-cell,
.grid .ui-grid-row,
.grid .ui-grid-cell,
.grid .ui-grid-cell .ui-grid-vertical-bar {
height: 22px !important;
font-size: 12px;
line-height: 20px;
}
.ui-grid-render-container-body .ui-grid-header-cell,
.ui-grid-render-container-left .ui-grid-header-cell,
ui-grid-header-cell {
height: 55px !important;
}
.ui-grid-filter-container {
padding: 1px 3px;
}
Scrolling works perfectly ok if the above CSS rules are removed.
So I either need to add more CSS rules or I need to use some API of the grid in order to set row height properly.
Any help will be much appreciated.
How do I change row height and keep scrolling smooth?
UPDATE:
Here is a comparison between a default grid and one with modified CSS:
http://plnkr.co/edit/x1nQGvpkY4bRMs9D09Ws?p=preview
try to scroll the rows up and down for each grid. The difference should be pretty obvious.
Take out the:
height: 22px !important;
from the css and add:
rowHeight:22
to the gridOptions.
I have the feeling that this is much smoother.
Forked Plunker
scope.gridOptions = {
rowHeight: 33
}
The best way of changing the row height is from the grid options.
Try add this to your css:
.ui-grid-viewport .ui-grid-cell-contents {
word-wrap: break-word;
white-space: normal !important;
}
.ui-grid-row, .ui-grid-cell {
height: auto !important;
}
.ui-grid-row div[role=row] {
display: flex ;
align-content: stretch;
}
Just alter grid class accordingly.
.grid{
height: 70vh;
}
Please see this link for example.
How can add a long caption under popup? For example, adding 3 lines like this:
we can add one line to title of tag and I tried to change this style
#cboxTitle {
position: absolute;
bottom: -25px;
left: 0px;
text-align: center;
width: 100%;
font-weight: bold;
color: #7C7C7C;
}
by adding height or top:800px, caption deisapear
This solution seems to work for me:
$(document).bind('cbox_complete', function(){
var cboxTitleHeight = $('#cboxTitle').height();
var cboxContentHeight = $('#cboxContent').height();
var cboxWrapperHeight = $('#cboxWrapper').height();
var colorboxHeight = $('#colorbox').height();
$('#cboxMiddleLeft, #cboxMiddleRight, #cboxContent').css('height', (cboxContentHeight + cboxTitleHeight) + 'px');
$('#cboxWrapper').css('height', (cboxWrapperHeight + cboxTitleHeight) + 'px');
$('#colorbox').css('height', (colorboxHeight + cboxTitleHeight) + 'px');
});
I also found this solution https://gist.github.com/eddyyanto/1620742 , but doesn't seem to work with v.1.5.x of colorbox.
Have you tried using this?
#cboxTitle {
position: absolute;
bottom: -25px;
left: 0;
text-align: right; /* MODIFIED */
width: 600px; /* MODIFIED */
font-weight: bold;
color: #7C7C7C;
word-break: break-word; /* ADDED */
margin-right: 100px; /* ADDED */
margin-left: 100px; /* ADDED */
}
This will allow for 2 lines of text!
Then to allow for more room remove for another line remove the following piece of CSS from the above. ( Use "/* CSS HERE */" to comment out so you can keep the code!) Example below
/* bottom: -25px; */
After that it will take a little fiddling around to get the "image 3 of 3" part moved :)
Hope this helps

Convenient tool for SVG encoding url-encoder
Making use of CSS sprites and data uri gives extra interesting benefits like fast loading and less requests AND we get IE8 support by using image/base64:
Codepen sample using SVG
HTML
<div class="div1"></div>
<div class="div2"></div>
CSS
.div1:after, .div2:after {
content: '';
display: block;
height: 80px;
width: 80px;
background-image: url(data:image/svg+xml,%3Csvg%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%20version%3D%221.1%22%20height%3D%2280%22%20width%3D%22160%22%3E%0D%0A%20%20%3Ccircle%20cx%3D%2240%22%20cy%3D%2240%22%20r%3D%2238%22%20stroke%3D%22black%22%20stroke-width%3D%221%22%20fill%3D%22red%22%20%2F%3E%0D%0A%20%20%3Ccircle%20cx%3D%22120%22%20cy%3D%2240%22%20r%3D%2238%22%20stroke%3D%22black%22%20stroke-width%3D%221%22%20fill%3D%22blue%22%20%2F%3E%0D%0A%3C%2Fsvg%3E);
}
.div2:after {
background-position: -80px 0;
}
For IE8, change to this:
background-image: url(data:image/png;base64,data......);
To extend further this topic. In case you want to add Font Awesome 5 icons you need to add some extra CSS.
Icons by default have classes svg-inline--fa and fa-w-*.
There are also modifier classes like fa-lg, fa-rotate-* and other. You need to check svg-with-js.css file and find proper CSS for that.
You need to add your own color to css icon otherwise it will be black by default, for example fill='%23f00' where %23 is encoded #.
h1::before{
/* svg-inline--fa */
display:inline-block;
font-size:inherit;
height:1em;
overflow:visible;
vertical-align:-.125em;
/* fa-w-14 */
width:.875em;

Be careful all of the other answers have some problem in IE.
Lets have this situation - button with prepended icon. All browsers handles this correctly, but IE takes the width of the element and scales the before content to fit it. JSFiddle
#mydiv1 { width: 200px; height: 30px; background: green; }
#mydiv1:before {
content: url("data:url or /standard/url.svg");
}
Solution is to set size to before element and leave it where it is:
#mydiv2 { width: 200px; height: 30px; background: green; }
#mydiv2:before {
content: url("data:url or /standard/url.svg");
display: inline-block;
width: 16px; //only one size is alright, IE scales uniformly to fit it
}
The background-image + background-size solutions works as well, but is little unhandy, since you have to specify the same sizes twice.
The result in IE11:
Although this was many years ago, I'd like to also share this.
The answers above are correct, you can directly attach the encoded svg string into the css content property. For those having any issues with the URL it may be due to spaces and characters not valid for such, in that case paste your decoded SVG code into:
https://mothereff.in/url
Use the encoded SVG URL and it should work fine.

I just today noticed that a newspaper here used direct injection of the SVG into the ::before and ::after pseudo-elements to render stylized quotes for highlighted content in the article. I tried to find that paper's CMS via whatcms.org but to no avail. I can say however that the owner newspaper - a large national, even international, paper uses a CMS called DM Polopoly.
It seems so much more laborious to enter SVG data into the content element rather than blank the content and use the SVG as a background image. I wonder why they chose this method - what advantage went with this. I've seen some people on Google links who said it made it easy to manipulate the SVG image on hovering upon the pseudo-element . . . But I saw no killer example of this 'benefit'.
This article has a simpler method for inserting the SVG as content.
It uses a zoom property to get size adjustment for the image.
using a background mask image with empty content, you can control the color from within css: (Don't forget the position, width and height that you prefer)...!
background-color: red;
-webkit-mask-image: url(icon.svg);
mask-image: url(icon.svg);
content:'';
