Can you have background-image: linear-gradient( to center...); - html

I have a div with background-image: linear-gradient( to bottom, red, blue);
but I want the to bottom to be to center but it does not work.
wright, now it looks like this
I want it to look like this
Does anyone know how to do this pleas help me?

What you are showing is a classic border:
.box {
border:40px solid blue;
height:50px;
width:50px;
background:red;
}
<div class="box"></div>
But I suspect you want a color fading so what you want is a radial-gradient
.box {
height:200px;
width:200px;
background:radial-gradient(farthest-side,red,blue);
}
<div class="box"></div>
Or maybe like below:
.box {
height: 200px;
width: 200px;
background: linear-gradient(to right, blue, red, blue);
position: relative;
}
.box::before {
content: "";
display: block;
height: 100%;
background: linear-gradient(blue, red, blue);
clip-path: polygon(0 0, 100% 100%, 0 100%, 100% 0);
}
<div class="box"></div>
Or like this:
.box {
height: 200px;
width: 200px;
background:
linear-gradient(to top right , red, blue) top right,
linear-gradient(to top left , red, blue) top left ,
linear-gradient(to bottom left , red, blue) bottom left,
linear-gradient(to bottom right, red, blue) bottom right;
background-size:50% 50%;
background-repeat:no-repeat;
}
<div class="box"></div>
Also using box-shadow
.box {
height: 200px;
width: 200px;
background: red;
box-shadow: 0 0 50px 35px blue inset;
}
<div class="box"></div>

What you can do is to utilize multiple background gradients:
.item {
--outerColor: blue;
--innerColor: red;
width: 120px;
height: 120px;
background-color: var(--innerColor);
background-image: linear-gradient(to bottom, var(--outerColor) 25%, transparent 25%, transparent 75%, var(--outerColor) 75%), linear-gradient(to right, var(--outerColor) 25%, transparent 25%, transparent 75%, var(--outerColor) 75%);
}
<div class="item"></div>
Here's how it works:
Step 1: Make pure red background:
.item {
--innerColor: red;
width: 120px;
height: 120px;
background-color: var(--innerColor);
}
<div class="item"></div>
Step 2: Add horizontal stripe
.item {
--outerColor: blue;
--innerColor: red;
width: 120px;
height: 120px;
background-color: var(--innerColor);
background-image: linear-gradient(to bottom, var(--outerColor) 25%, transparent 25%, transparent 75%, var(--outerColor) 75%);
}
<div class="item"></div>
Step 3: Add vertical stripe
.item {
--outerColor: blue;
--innerColor: red;
width: 120px;
height: 120px;
background-color: var(--innerColor);
background-image: linear-gradient(to bottom, var(--outerColor) 25%, transparent 25%, transparent 75%, var(--outerColor) 75%), linear-gradient(to right, var(--outerColor) 25%, transparent 25%, transparent 75%, var(--outerColor) 75%);
}
<div class="item"></div>

I think you want like this.
#grad1 {
height: 200px;
width: 200px;
background:
linear-gradient(90deg, blue, rgba(0,255,0,0) 30%),
linear-gradient(180deg, blue, rgba(0,0,255,0) 30%),
linear-gradient(0deg, blue, rgba(0,255,0,0) 30%),
linear-gradient(270deg, blue, rgba(0,0,255,0) 30%),
linear-gradient(0deg, blue, red, red 50%),
linear-gradient(90deg, blue, red, red 50%),
linear-gradient(180deg, blue, red, red 50%),
linear-gradient(270deg, blue, red, red 50%);
}
<div id="grad1"></div>

CSS gradient (background and border)

I'm trying to style an <a> tag with a gradient background and a gradient border.
I followed a tutorial online and tweaked it with the right colours, however then realised it needs to set the background-image property in order to give the borders a gradient.
.btn-primary {
background-color: blue;
background-image: linear-gradient(to bottom, #f7931e 0%, #f15a24 100%), linear-gradient(to bottom, #f7931e 0%, #f15a24 100%);
background-position: 0 0, 100% 0;
background-repeat: no-repeat;
background-size: 10% 100%;
border-bottom: 4px solid #f15a24;
border-top: 4px solid #f7931e;
box-sizing: border-box;
margin: 50px auto;
}
Is there a way I can modify the code so that I can specify a different gradient for the background of the button?
you can use border-image for the border, and just use background-image for the background gradient. Just like this:
.btn-primary {
background-color: blue;
background-image: linear-gradient(to bottom, #f7931e 0%, #f15a24 100%), linear-gradient(to bottom, #f7931e 0%, #f15a24 100%);
background-position: 0 0, 100% 0;
background-repeat: no-repeat;
background-size: 10% 100%;
border-bottom: 4px solid #f15a24;
border-top: 4px solid #f7931e;
box-sizing: border-box;
margin: 50px auto;
border-image: linear-gradient(to left, #f7931e 0%, #f15a24 100%), linear-gradient(to bottom, #f7931e 0%, #f15a24 100%
}
You could probably apply your rule to a pseudo-element :before or :after and then position the pseudo-element over your anchor.

Hope that helps!
Here is a way to create the illusion of a gradient border using multiple background gradients:
.btn-primary {
display:inline-block;
padding:80px;
background: linear-gradient(to bottom, transparent 0, transparent 30px, blue 30px, white calc(100% - 30px), transparent calc(100% - 30px), transparent 100%), linear-gradient(to left, red 0%, yellow 100%);
background-repeat: no-repeat;
background-position: 30px 0, 0 0;
background-size: calc(100% - 60px), auto;
}

I'm trying to build a circle with 8 colors, could you please help me to tweak the code above?
Use following css:
div {
background: linear-gradient(45deg, lightgreen 50%, blue 50%),
linear-gradient(-45deg, green 50%, darkgreen 50%),
linear-gradient(-45deg, #e5e500 50%, yellow 50%),
linear-gradient(45deg, tomato 50%, red 50%);
background-position: 0% 0%, 100% 0%, 0 100%, 100% 100%;
}
div {
width: 200px;
height: 200px;
border-radius:100%;
background: linear-gradient(45deg, lightgreen 50%, blue 50%),
linear-gradient(-45deg, green 50%, darkgreen 50%),
linear-gradient(-45deg, #e5e500 50%, yellow 50%),
linear-gradient(45deg, tomato 50%, red 50%);
background-size: 50% 50%;
background-position: 0% 0%, 100% 0%, 0 100%, 100% 100%;
background-repeat: no-repeat;
}
<div></div>
div {
width: 200px;
height: 200px;
border-radius:100%;
background: linear-gradient(45deg, yellow 0%, yellow 50%, blue 50%, blue 100%), linear-gradient(135deg, gray 0%, gray 50%, green 50%, green 100%), linear-gradient(-45deg, black 0%, black 50%, #b2dba1 50%, #b2dba1 100%) , linear-gradient(-135deg, red 0%, red 50%, orange 50%, orange 100%);
background-size: 50% 50%;
background-position: 0% 0%,0% 100%, 100% 0%, 100% 100%;
background-repeat: no-repeat;
}
<div></div>
Or with something like this.
Here you can add as many slices you want.
But its a little bit longer than the other solutions.
If you want to read more about this here is the right place.
.pie {

}
.hold {

CSS color transition in triangles with linear gradient

I am working on a rectangular background which is divided into 2 triangles by a line from top left to bottom right, as shown in the pic.
What I want to achieve is color transition in each triangle:
In triangle ABD: pink becomes darker from left to right
In triangle ACD: blue becomes darker from left to right
Note: The width and height are not fixed to 600 and 250. I just use them for demo purpose.
HTML code:
<div class="background-wrapper">
<p class="float-left">A</p>
<p class="float-right">B</p>
<br><br><br><br><br><br><br><br><br><br><br><br><br><br>
<p class="float-left">C</p>
<p class="float-right">D</p>
</div>
CSS code:
.background-wrapper {
position: relative;
width: 600px;
height: 250px;
color: #FFFFFF;
padding: 20px 50px 80px 50px;
background: linear-gradient(to left bottom, pink 50%, blue 50%);
}
.float-left {
float: left;
}
.float-right {
float: right;
}
Demo jsfiddle here
One posibility, that is cross-browser but that gives washed colors, is to overlay the triangles with a semitransparent gradient that is white on one side and black in the other.
This effect gets much better using blend modes, but the support is lower.
.test {
width: 400px;
height: 300px;
background-image: linear-gradient(to left, rgba(0,0,0,.5), rgba(0,0,0,0) 40%,
rgba(255,255,255,0) 60%, rgba(255,255,255,.5)),
linear-gradient(to top right, blue 50%, fuchsia 50%);
}
<div class="test"></div>
I modified your code quite a bit from the original. I added two new elements to act as the background. May not be the solution you're looking for but off the top of my head this is what works.
Fiddle
.background-wrapper {
position: relative;
width: 600px;
height: 250px;
color: #FFFFFF;
padding: 20px 50px 80px 50px;
overflow: hidden;
}
.triangle {
position: absolute;
top: -65%;
right: -30%;
width: 125%;
height: 125%;
transform: rotate(26.5deg);
background: linear-gradient(to right, pink, #f44274);
}
.triangle.bottom {
top: initial;
right: initial;
left: -30%;
bottom: -64.8%;
background: linear-gradient(to right, blue, navy);
}
<div class="background-wrapper">
<div class="triangle top"></div>
<div class="triangle bottom"></div>
</div>
You can use more colors after you define the linear-gradient position, so you can do stuff like:
background: linear-gradient(to left bottom, deeppink 0%, pink 50%, blue 50%,midnightblue 100%);
Check your updated fiddle
.background-wrapper {
position: relative;
width: 800px;
height: 450px;
background: #ffffff;
/* Old Browsers */background: -moz-linear-gradient(45deg, #ffffff 0%, #6176ff 49%, #ff80d9 50%, #ffffff 100%);
/* FF3.6+ */background: -webkit-gradient(left bottom, right top, color-stop(0%, #ffffff), color-stop(49%, #6176ff), color-stop(50%, #ff80d9), color-stop(100%, #ffffff));
/* Chrome, Safari4+ */background: -webkit-linear-gradient(45deg, #ffffff 0%, #6176ff 49%, #ff80d9 50%, #ffffff 100%);
/* Chrome10+,Safari5.1+ */background: -o-linear-gradient(45deg, #ffffff 0%, #6176ff 49%, #ff80d9 50%, #ffffff 100%);
/* Opera 11.10+ */background: -ms-linear-gradient(45deg, #ffffff 0%, #6176ff 49%, #ff80d9 50%, #ffffff 100%);
/* IE 10+ */background: linear-gradient(45deg, #ffffff 0%, #6176ff 49%, #ff80d9 50%, #ffffff 100%);
/* W3C */filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#ffffff', endColorstr='#ffffff', GradientType=1 );
/* IE6-9 fallback on horizontal gradient */
}
.float-left {
float: left;
}
.float-right {
float: right;
}
you can specify the angle in the gradient. Try the above code. it works with width and height.

How can I render country flags as a ribbon, using CSS only?

I need to present some data. Each block of data needs a country flag. I would like to display the country flag, using a nice little hanging banner, like this:
This image is edited in paint, and the example I've used, comes from this page
This link right here, shows how to display flags of Europe++ in pure CSS. In my system, I only need Nordic flags, which are all represented by a cross.
From the codepen example:
#function cross($back, $main, $detail: $back){
#return linear-gradient(90deg, transparent 28%, $main 28%, $main 34%, transparent 34%),
linear-gradient(transparent 42%, $detail 42%, $detail 46%, $main 46%, $main 58%, $detail 58%, $detail 62%, transparent 62%),
linear-gradient(90deg, $back 25%, $detail 25%, $detail 28%, $main 28%, $main 34%, $detail 34%, $detail 37%, $back 37%);
}
If I derive this (and rotate it 90deg to fit my preferred orientation, I can get something like this:
HTML:
<div class="norway"></div>
CSS:
.norway{
background: linear-gradient(180deg, transparent 28%, blue 28%, blue 34%, transparent 34%),
linear-gradient(90deg, transparent 42%, white 42%, white 46%, blue 46%,
blue 58%, white 58%, white 62%, transparent 62%),
linear-gradient(180deg, red 25%, white 25%, white 28%, blue 28%, blue 34%,
white 34%, white 37%, red 37%);
height: 600px;
width: 400px;
}
The hanging banner example however, is not really displaying the element itself, merely its border. I like the split in the bottom, So I would like to be able to set the linear gradients on the different border sides individually, or somehow otherwise solve the problem. I have tried a few approaches, but I can't seem to make the gradients work on individual border sides.
Does anyone know how I can display my flags as split end ribbons, using only CSS?
By the way, the Czech Republic is easy...
UPDATE:
I was able to render a Norwegian version, but I had to make two elements. One displaying the flag in the background of an element, and another element over it, displaying only the bottom border, in the same color as the block background. It seems like a pretty fragile solution, though...
https://jsfiddle.net/azjctc1y/
Note: After looking at Joseph's answer, I'd suggest you to go with that but this is another way.
Instead of using border to create the flag, we can use background with linear-gradient images like in the below snippet.

Original Answer:
It is not 100% like the image provided in question or the ouput of your fiddle because the blue cross doesn't have the small triangular cut because I was trying create a cut that was transparent (so that you can use it on top of an element with any background). But if it is always going to be a grey background then that can also be done.
The below is the code that I have added:
.close-ribbon:after {
position: absolute;
content: "";
top: -1em;
right: 0;
height: 5em;
width: 3em;
background: linear-gradient(180deg, transparent 28%, blue 28%, blue 34%, transparent 34%), linear-gradient(90deg, transparent 40%, white 40%, white 46%, blue 46%, blue 58%, white 58%, white 62%, transparent 62%), linear-gradient(180deg, red 25%, white 25%, white 28%, blue 28%, blue 34%, white 34%, white 37%, red 37%), linear-gradient(to bottom right, red 50%, transparent 55%), linear-gradient(to top right, transparent 45%, red 50%);
background-size: 3em 4em, 3em 4em, 3em 4em, 1.25em 1em, 1.2em 1em;
background-position: 0% 0%, 0% 0%, 0% 0%, 0% 100%, 100% 100%;

You have a great base to go on. It just needs a few tweaks here and there. (Making individual styles for flags is going to be a colossal pain though). There's just a few places you could improve it. In most cases when using absolute positioning, you may want to have whatever you are positioning align with some edge of the parent element. For that you can use negative values like left: -1em or whatever, but a lot of times, it's more robust to leave left auto and set the right attribute to 100%. You also set the bottom border to right:0. In throwing it in this answer I discovered that the font size difference caused it to be aligned incorrectly. One way you can fix that is to give it a left:50% with a negative margin equal to the left border. In this case it's 1.5em. A few changes, but it's all about understanding and leveraging top, right, bottom, and left to their fullest potential, which includes percent based values.
Hope it helps!

Inserted a div into the anchor tag and styled a before and after content to display the blue cross. Used a + symbol to display the white underneath cross.

EDIT
Just saw your fiddle. Looks good! Was just going to suggest something like that but decided to at least build somewhat of a working model.

CSS: How to flip this linear-gradient?

I have this code which creates a line of triangles. It's quite nice, but I want it inverse. Instead the edges to be up, to be down. I tried like for 30 minutes to make it work... I just don't get the linear-gradient.
Here is the current output
And I want it to be like this:
Here is the code:
background-image: linear-gradient(45deg, #E4E1D6 25%, transparent 25%,transparent),
linear-gradient(-45deg, #E4E1D6 25%, transparent 25%, transparent),
linear-gradient(45deg, transparent 75%, #E4E1D6 75%),
linear-gradient(-45deg, transparent 75%, #E4E1D6 75%);
width: 100%;
background-position: 0px 7px;
position: relative;
top: -47px;
height: 7px;
background-size: 10px 12px;
Thanks for help.
Simply change background-position: 0px 7px to background-position: 0 0
div {
background: linear-gradient(45deg, #E4E1D6 25%, transparent 25%,transparent),
linear-gradient(-45deg, #E4E1D6 25%, transparent 25%, transparent),
linear-gradient(45deg, transparent 75%, #E4E1D6 75%),
linear-gradient(-45deg, transparent 75%, #E4E1D6 75%);
width: 100%;
background-position: 0 0;
position: relative;
height: 7px;
background-size: 10px 12px;
}
