I want to create the background image of the attached div element with CSS (or SVG).
div.target {
background-image: linear-gradient(
to right bottom,
transparent 50%,
#00BCD4 50%
);
Background image of the div element I want to create with CSS (or SVG)
We can do this using multiple background image gradients like in the below snippet. The darker shade is assigned as the background color to the element. Then two background image layers created using gradients are placed in such a way that they produce the desired effect. Adding a partially transparent layer of white color above the darker shade will produce a lighter shade.
The background-size of the second layer should be smaller and its background-position should be at the left-bottom side of the element.
div {
height: 200px;
background-color: rgb(20,203,194);
background-image: linear-gradient(to top left, rgba(255,255,255,0.25) 50%, rgba(255,255,255,0) 50%), linear-gradient(to top right, rgba(255,255,255,0.25) 50%, rgba(255,255,255,0) 50%);
background-size: 100% 100%, 50px 50px;
background-position: left top, left bottom;
background-repeat: no-repeat;
}
<div></div>
Angled CSS gradients are known to produce slightly jagged (or uneven or rough) edges and that can be avoided by offsetting the color stop point a bit like in the below demo.
div {
height: 200px;
background-color: rgb(20,203,194);
background-image: linear-gradient(to top left, rgba(255,255,255,0.25) 50%, rgba(255,255,255,0) calc(50% + 1px)), linear-gradient(to top right, rgba(255,255,255,0.25) 50%, rgba(255,255,255,0) calc(50% + 1px));
background-size: 100% 100%, 50px 50px;
background-position: left top, left bottom;
background-repeat: no-repeat;
}
<div></div>
You can do this with :before and :after pseudo elements.
div {
position: relative;
width: 500px;
height: 100px;
background: #0BC7BE;
}
div:after {
position: absolute;
border-style: solid;
border-width: 0 0 100px 500px;
border-color: transparent transparent rgba(255, 255, 255, 0.3) transparent;
right: 0;
top: 0;
content: "";
}
div:before {
position: absolute;
border-style: solid;
border-width: 50px 0 0 70px;
border-color: transparent transparent transparent rgba(255, 255, 255, 0.3);
left: 0;
bottom: 0;
content: "";
}
<div></div>

There are four lines over the background. They are visible in overall sections but not over images.
How to make this?
It is as easy as this
body{
background: linear-gradient(90deg, #eee 1%, transparent 1%) 1px 0, #fff;
background-size: 200px 1px;
}
DEMO: https://codepen.io/anon/pen/VMzwNw
These and many other backgrounds can be generated using this site -> http://lea.verou.me/css3patterns/#stairs
You can use CSS linear gradients and multiple backgrounds to achieve this. Here's an example:
div {
height: 100px;
background-color: transparent;
background-size: 25% 100%;
background-repeat: repeat-x;
background-image: linear-gradient(to right, black 1px, transparent 1px);
background-position: 12.5%;
}
<div>
</div>
The gradient draws a vertical line, whereas background-size, background-position and background-repeat combined make the vertical line repeat.
Here's an example with a background image and the vertical lines:
div {
height: 100px;
background-color: transparent;
background-size: 25% 100%, cover;
background-repeat: repeat-x, no-repeat;
background-image: linear-gradient(to right, black 1px, transparent 1px), url(http://lorempixel.com/400/200/);
background-position: 12.5%, center;
}
<div>
</div>
I have this gradient:
div {
height: 100px;
width: 100px;
background: linear-gradient(-60deg, transparent 63%, white 63%),
linear-gradient(60deg, transparent 63%, white 63%),
linear-gradient(to top, blue, blue);
}
I want to know a) how do I flip it so it's coming from the top and b) how to rewrite without the third part (to top, blue, blue) since I just want a single color and it seems wrong this way.
For the first part, you can try this
div {
height: 100px;
width: 100px;
background: linear-gradient(120deg, transparent 63%, white 63%),
linear-gradient(-120deg, transparent 63%, white 63%),
blue;
}
For the second part, try this
div {
height: 0;
width: 0;
border-left: 50px solid transparent;
border-right: 50px solid transparent;
border-top: 100px solid blue;
}
Hope this will help you ..
This can be achieved with just two linear-gradient images by setting the appropriate background-size and background-position for the images (like in the below snippet).
div {
height: 100px;
width: 100px;
background: linear-gradient(to top right, transparent 49.5%, blue 50.5%),
linear-gradient(to top left, transparent 49.5%, blue 50.5%);
/* the difference in color stops is to produce smoother edges */
background-size: 50% 95%; /* X size should be 50%, Y size can be as you wish */
background-position: left top, right top; /* don't change */
background-repeat: no-repeat; /* don't change */
}
/* just for demo */
div {
border: 1px solid;
display: inline-block;
vertical-align: bottom;
}
div:nth-child(2), div:nth-child(4) { width: 150px; }
div:nth-child(2), div:nth-child(3) { height: 150px; }
<div></div>
<div></div>
<div></div>
<div></div>
I've changed the gradient to the to [side] [side] syntax because it helps in achieving responsive output. (You can refer to this answer of mine for a detailed explanation about why that change helps.)
In the below snippet, I've given two different colors for the gradient so that you could visually see what is happening.
div {
height: 100px;
width: 100px;
background: linear-gradient(to top right, transparent 49.5%, blue 50.5%), linear-gradient(to top left, transparent 49.5%, green 50.5%);
background-size: 50% 95%;
background-position: left top, right top;
background-repeat: no-repeat;
}
<div></div>
I have been seeing a lot of new websites that have a zigzagged border in between an image and a div. When you open the image in a new tab the zigzag is not there, so it was created either with CSS3 or HTML5. Does anyone know how it is done?
Here are some examples:
http://themeforest.net/item/hungry-a-onepage-html-restaurant-template/full_screen_preview/9855248ref=freshdesignweb
http://designwp.com/yummie/brown/index.html
Wait for them to load.
zig zag borders are made using linear-gradient
50% is the blur
315deg is the rotation of right side
45deg is the rotation of left side
background size is the width and placement of the triangle
div {
width: 100%;
height: 50px;
background-size: 25px 120%;
background-image: linear-gradient(315deg, red 50%, rgba(0, 0, 0, 0) 50%),
linear-gradient(45deg, red 50%, black 50%);
}
<div></div>
you can also change the angle of rotation by changing the deg values
div {
width: 100%;
height: 50px;
background-size: 25px 150%;
background-image: linear-gradient(297deg, red 50%, rgba(0, 0, 0, 0) 50%),
linear-gradient(63deg, red 50%, black 50%);
}
<div></div>
First one is built with repeatable background image, and secound one with :before pseudo element:
.ss-style-top::before {
position: absolute;
content: '';
left: 0;
width: 100%;
height: 30px;
background-size: 25px 100%;
top: 0;
background-image: linear-gradient(315deg, #FFF 50%, transparent 50%),
linear-gradient(45deg, #FFF 50%, transparent 50%);
margin-top: -30px;
z-index: 100;
}
Here is the link of background image from first example: http://www.cssvillain.com/hungry/images/assets/parallax-bottom-alt.png
When i create background gradient like this:
background: radial-gradient(ellipse at center, #ffffff 0%,#ffffff 59%,#ededed 100%);
I get ellipse that is inside the div, and conform to shape of div. So if div is large in height then ellipse would be stretched vertically. If div is a square then ellipse would be like a circle. That's fine, i want to control height of ellipse.
The exact question can be addressed by combining the last 2 answers: circle gradient and adjusting the background size.
Something like this:
div {
width: 300px;
height: 100px;
background: radial-gradient(circle, white 0%, red 50%, black 100%);
background-size: 100% 200%;
background-position: 0% 50%;
}
<div></div>
I find it less of a hassle than nested divs, and by playing with the background-position and size values, you can get some pretty cool effects!
Use a div with overflow set to hidden, and a div inside of it absolutely positioned with a fixed height.
#outer {
height: 100px;
overflow: hidden;
position: relative;
width: 200px;
}
#inner {
background: radial-gradient(ellipse at center, #1e5799 0%, #2989d8 50%, #207cca 51%, #7db9e8 100%);
bottom: 0;
height: 150px;
position: absolute;
width: 200px;
}
<div id="outer">
<div id="inner"></div>
</div>
You can play with the background dimensions and position:
div {
width: 300px;
height: 100px;
background: radial-gradient(ellipse at center, white 0%, red 100%);
background-size: 100% 200%;
background-position: 0% 50%;
}
demo
You can try circle instead of ellipse:
Demo on dabblet
.rect2 {
width: 600px;
height: 100px;
line-height: 100px;
text-align: center;
background: radial-gradient(circle, #ffffff 0%, #ffffff 59%, #dcdcdc 100%);
}
Basically I want to create a shape in CSS only (so no images) that is the opposite of a heart shape. I don't know how to explain it properly so here is an image:
The blue is the background, as you can see, but the shape that I want to create is not a heart, it is the shape of the black rectangle.
If I would have the following shape (THE GRAY NOT THE BLACK)
I could duplicate it and then rotate it, that would give me the shape I am looking for.
Heart shape cut out using box-shadow
Let's create this — the blue is the background color of <body>
The pieces
Feel free to skip directly to the complete demo at the bottom of this answer :)
1 - The rounded corners
The rounded top left and top right corners are created with box-shadow on the two pseudo elements with border-radius: 50% — .heart:before and .heart:after — They form two crescent shapes that look like this:
2 - The angle
The angled shape is created by the box-shadow on .heart. Combined with the two circles, it looks like this:
3 - The filler
We now need to fill in the gaps. This is done by the pseudo elements of the .box-shape container — .shape-box:before and .shape-box:after. The excess is cut-off neatly with overflow: hidden on the .shape-box. Combined with our pieces above, they look like this:
The Complete Example
Combine it all together and we get this nicely cut out heart shape. It is all contained in .shape-box.
body {
background: #00A2F6;
}
.shape-box {
height: 504px;
width: 504px;
position: relative;
margin: 100px;
overflow: hidden;
}
.shape-box:before,
.shape-box:after {
content: '';
display: block;
height: 100px;
width: 120px;
background: #2B2B2B;
transform: rotate(45deg);
left: 190px;
position: absolute;
top: 40px;
}
.shape-box:after {
width: 760px;
height: 750px;
box-shadow: inset 0 0 0 220px #2B2B2B;
top: -150px;
left: -130px;
background: none;
}
.heart {
transform: rotate(45deg);
height: 357px;
width: 356px;
box-shadow: inset 0 0 0 50px #2B2B2B;
position: absolute;
left: 74px;
top: 34px;
}
.heart:before,
.heart:after {
content: '';
display: block;
width: 151px;
height: 151px;
border-radius: 50%;
box-shadow: -40px -15px 0 20px #2B2B2B;
position: absolute;
left: 50px;
top: 157px;
}
.heart:after {
box-shadow: -15px -40px 0 21px #2B2B2B;
left: 156px;
top: 51px;
}
<div class="shape-box">
<div class="heart"></div>
</div>
This can be done with a combination of svg gradients, multiple backgrounds, and a little creative tiling/placement. Sample CSS from my working jsfiddle (without vendor prefixes, i.e. -webkit and -moz):
height: 400px;
width: 400px;
background-image:
radial-gradient(75% 85.5%, circle, transparent 25%, black 26%),
radial-gradient(25% 85.5%, circle, transparent 25%, black 26%),
linear-gradient(225deg, transparent 25%, black 25%),
linear-gradient(135deg, transparent 25%, black 25%);
background-size: 200px 200px;
background-position: top left, top right, bottom left, bottom right;
background-repeat: no-repeat;
This makes a heart-shaped cutout in the middle of a 400px square element. It can be modified to fit whatever size element you want.
Update: here’s a more complex fiddle that uses six gradients instead of four, but looks a bit nicer.
Based on the work that Mark Hubbart did I was able to push this to a slightly more advanced form in this fiddle
This is not 100% complete yet as it will need some media queries to work across more browsers but it does show the start of a much more flexible working for the same goal.
