I am having issues with cross browser rendering of CSS3 gradients. This is happening when I am trying to create a gradient from transparent colour to white.
The file I am using to test with is:
http://f.cl.ly/items/0E2C062x3O161b09261i/test.html
CSS used is:
background-image: linear-gradient(top, rgba(255,255,255,0) 0%, rgba(255,255,255,1) 50%, rgba(255,255,255,1) 100%);
background-image: -o-linear-gradient(top, rgba(255,255,255,0) 0%, rgba(255,255,255,1) 50%, rgba(255,255,255,1) 100%);
background-image: -moz-linear-gradient(top, rgba(255,255,255,0) 0%, rgba(255,255,255,1) 50%, rgba(255,255,255,1) 100%);
background-image: -webkit-linear-gradient(top, rgba(255,255,255,0) 0%, rgba(255,255,255,1) 50%, rgba(255,255,255,1) 100%);
background-image: -ms-linear-gradient(top, rgba(255,255,255,0) 0%, rgba(255,255,255,1) 50%, rgba(255,255,255,1) 100%);
Rending looks like what I want in Safari 6 (mac):
Chrome rendering fades to gray colour before it fades to white (Firefox renders this way also on mac os):
Any ideas or suggestions on why this odd rendering might be?
I've encountered this as well. I'm not sure why it happens, but here's what I've used in my own projects as a workaround:
background-image: -webkit-linear-gradient(top, rgba(255,255,255,0.001) 0%, #fff 5%, #fff 100%);
Instead of giving Chrome a "transparent" value, give it something very, very close to transparent.
Edit: I forgot to post a link to my own version, which renders as expected in Chrome 21 (Windows 7).
The CSS I pasted in here was wrong, I was editing the wrong file DOH!
Original CSS not working
background-image: linear-gradient(top, transparent 0%, #fff 5%, #fff 100%);
background-image: -o-linear-gradient(top, transparent 0%, #fff 5%, #fff 100%);
background-image: -moz-linear-gradient(top, transparent 0%, #fff 5%, #fff 100%);
background-image: -webkit-linear-gradient(top, transparent 0%, #fff 5%, #fff 100%);
background-image: -ms-linear-gradient(top, transparent 0%, #fff 5%, #fff 100%);
CSS that fixed the problem
background-image: linear-gradient(top, rgba(255,255,255,0) 0%, #fff 5%, #fff 100%);
background-image: -o-linear-gradient(top, rgba(255,255,255,0) 0%, #fff 5%, #fff 100%);
background-image: -moz-linear-gradient(top, rgba(255,255,255,0) 0%, #fff 5%, #fff 100%);
background-image: -webkit-linear-gradient(top, rgba(255,255,255,0) 0%, #fff 5%, #fff 100%);
background-image: -ms-linear-gradient(top, rgba(255,255,255,0) 0%, #fff 5%, #fff 100%);
Problem being transparent isn't a colour, it is black with 0 alpha, setting to specifically white with 0 alpha fixes the issue. (thanks #carisenda)
This still points on inconsistencies with how browser vendors are dealing with alpha transparency in CSS3 gradients.
The trick with a color besides white (and with white actually) is to rgba the actual color that is fading.
background-image: linear-gradient(to right,
rgba(111,174,249, 0) 0%,
rgba(111,174,249, 0) 80%,
rgb (111,174,249) 100%);
In case the color being used is hex (like #6faef9) use a hex to rgba converter to convert the color.
The same problem is encountered on native IOS as well:
iOS White to Transparent Gradient Layer is Gray
https://betterprogramming.pub/the-proper-way-of-creating-a-transparent-gradient-layer-in-ios-b082daa866b1layer-is-gray
I notice that on CSS the solution is to use white color instead of black and then add 0 transparency
rgb(255 255 255/0)
I've recently encountered the same issue regarding transparency on safari. What worked for me was substituting the css into the compiled safari css.
This didn't work for me
background-image: linear-gradient(to top, rgba(56,56,56,1) 5%, rgba(255,255,255,0.001) 100%)
This did work for me
background-image: linear-gradient(0deg,#383838 5%, hsla(0, 0%, 20%, 0) 100%)
I have CSS for Mozilla
background-image: -moz-linear-gradient(center top,
hsl(0, 0%, 20%), hsl(0, 0%, 13%));
and I need this CSS to work with WebKit browsers & IE as well.
I use this gradient generator.
Example:
background-image: -webkit-gradient(
linear,
left top,
left bottom,
color-stop(0, #BF50D8),
color-stop(1, #70CDFF)
);
background-image: -o-linear-gradient(bottom, #BF50D8 0%, #70CDFF 100%); //Opera
background-image: -moz-linear-gradient(bottom, #BF50D8 0%, #70CDFF 100%); //Firefox
background-image: -webkit-linear-gradient(bottom, #BF50D8 0%, #70CDFF 100%); //Safari & Chrome
background-image: -ms-linear-gradient(bottom, #BF50D8 0%, #70CDFF 100%); //IE
background-image: linear-gradient(to bottom, #BF50D8 0%, #70CDFF 100%);
For Internet Explorer it should be background-image: -ms-linear-gradient
Ms from Microsoft of course.
And for safari:
-webkit-linear-gradient
Here is how to add gradient crossbrowser:
background: -o-linear-gradient();
background: -webkit-gradient(); /* Older webkit syntax */
background: -webkit-linear-gradient();
background: -ms-linear-gradient();
Example on webkit:
background: -webkit-gradient(linear, 0% 0%, 0% 100%, from(), to());
I have created a simple css bar with colour stops using the following:
#testing{
width:100%;
height:40px;
background-image: -webkit-linear-gradient(left, #034a96 80%, #eab92d 50%);
background-image: -moz-linear-gradient(top, #034a96 50%, #eab92d 51%);
background-image: -ms-linear-gradient(top, #034a96 50%, #eab92d 51%);
background-image: -o-linear-gradient(top, #034a96 50%, #eab92d 51%);
background-image: linear-gradient(top, #034a96 50%, #eab92d 51%);
-webkit-border-radius: 15px;
-moz-border-radius: 15px;
border-radius: 15px;
}
What I would like to do is have the first 80% of the bar is have a gradient that goes from the top with colour #034a96 to #0663c7 and then just that gradient colouring 50% of the bar. Then with the other 51% I have another gradient from the top with #eab92d to #c79810. What I'm asking is if it is possible to have multiple gradients with in each other eg:
background-image: -webkit-linear-gradient(left, top #034a96 to #0663c7 50%, top #eab92d to #c79810 51%);
Or something along those lines. I hope I'm being clear with everything. Thanks in advance
Yes, you can.
One simple example (not exactly your colourset, but it shows the plan):
background: #b8e1fc; /* Old browsers */
background: -moz-linear-gradient(top, #b8e1fc 0%, #a9d2f3 10%, #90bae4 25%, #90bcea 37%, #90bff0 50%, #6ba8e5 51%, #a2daf5 83%, #bdf3fd 100%); /* FF3.6+ */
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#b8e1fc), color-stop(10%,#a9d2f3), color-stop(25%,#90bae4), color-stop(37%,#90bcea), color-stop(50%,#90bff0), color-stop(51%,#6ba8e5), color-stop(83%,#a2daf5), color-stop(100%,#bdf3fd)); /* Chrome,Safari4+ */
background: -webkit-linear-gradient(top, #b8e1fc 0%,#a9d2f3 10%,#90bae4 25%,#90bcea 37%,#90bff0 50%,#6ba8e5 51%,#a2daf5 83%,#bdf3fd 100%); /* Chrome10+,Safari5.1+ */
background: -o-linear-gradient(top, #b8e1fc 0%,#a9d2f3 10%,#90bae4 25%,#90bcea 37%,#90bff0 50%,#6ba8e5 51%,#a2daf5 83%,#bdf3fd 100%); /* Opera 11.10+ */
background: linear-gradient(to bottom, #b8e1fc 0%,#a9d2f3 10%,#90bae4 25%,#90bcea 37%,#90bff0 50%,#6ba8e5 51%,#a2daf5 83%,#bdf3fd 100%); /* W3C */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#b8e1fc', endColorstr='#bdf3fd',GradientType=0 ); /* IE6-9 */
This code doesn't create multi-step gradients in IE.
Up to IE9, these aren't possible at all (only simple gradients), but IE9 supports SVG data. It's a bit complicated to write, but you should have a look at http://www.colorzilla.com/gradient-editor. It's an online-tool for creating CSS code for gradients. It also supports SVG gradients for IE9.
I am using rendering plugin to generate pdf in grails.
I am using a background color which is prepared by css. code is here.

/* IE9 SVG, needs conditional override of 'filter' to 'none' */

}
it is in style tag. its working fine when I see it at browser but when I am generating pdf color is not render. where am I wrong.
The rendering plugin uses itext 2.1.0 for creating the pdf. That is a very old version of itext (probably the last open source) and does not support CSS3 styles very well. Look at this other discussion Compare these products for PDF generation with Java given requirements inside: iText, Apache PDFBox or FOP? for other available options.
Is there any way to create a gradient background using nothing but CSS?
You can see an example of what I want to achieve on this website.
Use this in your CSS:
background-image: -o-linear-gradient(bottom, rgb(254,133,107) 24%, rgb(35,171,17) 62%);
background-image: -moz-linear-gradient(bottom, rgb(254,133,107) 24%, rgb(35,171,17) 62%);
background-image: -webkit-gradient(linear, left bottom, left top, color-stop(0.24, rgb(254,133,107)), color-stop(0.62, rgb(35,171,17)));
background-image: -webkit-linear-gradient(bottom, rgb(254,133,107) 24%, rgb(35,171,17) 62%);
background-image: -ms-linear-gradient(bottom, rgb(254,133,107) 24%, rgb(35,171,17) 62%);
/* This last line is all you need for modern browsers */
background-image: linear-gradient(bottom, rgb(254,133,107) 24%, rgb(35,171,17) 62%);

Simple and easy to make. Try this link
/* IE10 Consumer Preview */
background-image: -ms-linear-gradient(top, #FCFEFF 0%, #AF00EF 100%);
/* Mozilla Firefox */
background-image: -moz-linear-gradient(top, #FCFEFF 0%, #AF00EF 100%);
/* Opera */
background-image: -o-linear-gradient(top, #FCFEFF 0%, #AF00EF 100%);
/* Webkit (Safari/Chrome 10) */
background-image: -webkit-gradient(linear, left top, left bottom, color-stop(0, #FCFEFF), color-stop(1, #AF00EF));
/* Webkit (Chrome 11+) */
background-image: -webkit-linear-gradient(top, #FCFEFF 0%, #AF00EF 100%);
/* W3C Markup, IE10 Release Preview */
background-image: linear-gradient(to bottom, #FCFEFF 0%, #AF00EF 100%);
Use background-image with linear-gradient() or radial-gradient().
.linear-gradient {
background-image: linear-gradient(to bottom, #000077, #65A5FF);
}
.radial-gradient {
background-image: radial-gradient(#000077, #65A5FF);
}
div {
width: 100%;
height: 200px;
}
<h1>Linear gradient</h1>
<div class="linear-gradient"></div>
<h1>Radial gradient</h1>
<div class="radial-gradient"></div>
According to caniuse.com, CSS gradients are supported by all major browsers. If you have to support IE <= 9, use plain-color or image background fallback. If you have to support Android Browser <= 4.3, also use prefixed version (-webkit-linear-gradient).
.bckgrnd {
background-color:Green;
background-image: -webkit-gradient(linear, 0% 0%,0% 0%, from(Green), to(Yellow));
background-image: -webkit-linear-gradient(top, Green, Yellow);
background-image: -moz-linear-gradient(top, Green, Yellow);
background-image: -ms-linear-gradient(top, Green, Yellow);
background-image: -o-linear-gradient(top, Green, Yellow);
}

But there are also images and other things on this website, so if you want to copy the style, look how they have done it and try to implement it on your own ! There is also a website which has pretty neet background pattern's which, combined with gradients look absolutely rich and beautiful:

A simple sample code for gradients which will be displayed in every browser:
background: rgb(243,226,199);

Add two div tag and give background color link this
<div style="background-color:black"> </div>
<div style="background: -moz-linear-gradient(top, #55aaee, #003366);"> </div>
This is not exact syntax this is an idea that how u can do
