Css angled corners

If you were to create a rectangular box outline around the content on your web page using Cascading Style Sheets CSSthe default is that your box borders will have pointed right-angled corners. To get rounded corners for the box, many webmasters in the past have resorted to using images to give the appearance of curved corners.

This article shows you how to achieve the same effect using CSS. It also discusses some of the limitations to using CSS for this purpose at this time. The latter is written in plain English, and is more suitable for the beginner.

The CSS property for creating rounded corners is known as border-radius. It is part of CSS Level 3, which at the time this article was first written, is still in its "Working Draft", meaning that it has not been formally adopted as a standard yet. Although it has not been officially standardised "standardized" in certain variants of Englishthe property appears to have already been implemented in the latest versions of all modern web browsers.

This paragraph is enclosed in a box that uses the CSS3 border-radius property. You should be able to see the effect if you're using the current versions of Firefox, Chrome, Safari, Microsoft Edge and Internet Explorer version 9 and later. As "radius" suggests, CSS imagines that the curve is part of an ellipse, that is, an oval or a circle. Since I only provided one value above, the browser draws a circular arc with a radius of 20 pixels for each corner of the box.

The picture below shows the top right corner of the box, with the radius marked. Other types of curved corners are also possible. If you supply different values for the horizontal and vertical radius, you get the corner of an oval rather than a circle. For example, the rule below creates corners where the horizontal radius if that's the right word is 40 pixels and the vertical radius is 20 pixels.

In other words the shape is more like that of an oval, as illustrated in the picture below of the top right corner of the box not drawn to scale. As I'm sure you've noticed from above, the first value, before the slash, specifies the horizontal radius and the second value, after the slash, the vertical.

If you do not want to create a symmetrical box, but want each corner to have different curvatures, the easiest way to do this is to use the following self-explanatory properties:. The values for individual properties listed above are exactly the same as that for border-radius except that they control only one corner of your box. Update : you can ignore this section.This attribute is created in and gained widespread usage amongst web developers which provides easy styling for different elements.

We will start with a single value example where the provided value will be applied to all four corners. In this example, we will apply the border-radius as 15 pixels with 15 px like below. We can also use two parameters here the first parameter is used for the top-left and bottom-right corners and the second value will be used for top-right and bottom-left corners.

We can use three values that will be used to set border-radius. The first value will be used to set top-left, the second value for top-right and bottom-left corners and third value will set the bottom-right corner. We can also provide four values where each of them will be used for a single corner. First value will be for the top-left corner, the second value will be for the top-right corner, the third corner will be for bottom-right corner and the forth corner will be for bottom-left corner.

While rounding corners of the HTML elements we generally use pixels as parameter or size unit. Pixel is defined with the px after the size like below. We can also use other unit types like a percentage in order to specify the round size.

We can also specifically set the corner we want to round.

If we want to round the top left corner we can use border-top-left-radius CSS attribute like below. If we want to round the top right corner we can use border-top-right-radius CSS attribute like below.

If we want to round the bottom left corner we can use border-bottom-left-radius CSS attribute like below. If we want to round the bottom right corner we can use border-bottom-right-radius CSS attribute like below.Learn Development at Frontend Masters.

You can make them with a single div. The idea is a box with zero width and height. The actual width and height of the arrow is determined by the width of the border. In an up arrow, for example, the bottom border is colored while the left and right are transparent, which forms the triangle. Frontend Masters is the best place to get it. And say, if i just need to make sure that the bottom part of the triangle is not there, how do i do that as well?

Hey Ayush! You could change to color of the triangle by changing the colors in the visible border. Hey thank you very much! It worked! But can you tell me how to give a border to this type of triangle? As it is only made up of the border of a div!! Hey Tarun! There are several pages which show how to put arrows on tooltips, etc but they left me completely mystified as to how they worked. Now at last, thanks to this page, I understand! Thanks for the reminder! Thanks, Otto. It appears to be more noticeable in Webkit, for some reason—not sure why.

Cool trick, I tried it first after seeing it elsewhere. Then I came across the ivy-leaf trick on this website, and if you want the triangle to scale with the text, change the ivy leaf to a triangle.

You can use those triangles to create Real-time 3D objects in IE6. Yes, IE6! I noticed a small issue with this technique in Firefox 5.

Other browsers continue to render the triangles fine even after this border-style adjustment. Was working my mind through the reason for the strange micro-border!

Is anyone else getting this? The line will always look a little jagged. If you want truly straight lines at whatever angle, you might want to explore SVG.

You do some limited drop shadows using a pseudo-element. A little rotation looks nice with this effect, too. I saw it in a NetTuts piece recently. Is it possible to use this on a [submit] button? I tried creating the same using two div and i got the same.The linear-gradient CSS function creates an image consisting of a progressive transition between two or more colors along a straight line. Additional CSS image functions include imageimage-setand cross-fade.

Images can be used with numerous CSS properties, such as background-image, border-image, content, cursor, and list-style-image. As with any gradient, a linear gradient has no intrinsic dimensions ; i. Its concrete size will match the size of the element it applies to. For this reason, linear-gradient won't work on background-color and other properties that use the CSS data type represents a color in the sRGB color space. A linear gradient is defined by an axis—the gradient line —and two or more color-stop points.

Each point on the axis is a distinct color; to create a smooth gradient, the linear-gradient function draws a series of colored lines perpendicular to the gradient line, each one matching the color of the point where it intersects the gradient line. The gradient line is defined by the center of the box containing the gradient image and by an angle.

The colors of the gradient are determined by two or more points: the starting point, the ending point, and, in between, optional color-stop points.

The starting point is the location on the gradient line where the first color begins. The ending point is the point where the last color ends. Each of these two points is defined by the intersection of the gradient line with a perpendicular line passing from the box corner which is in the same quadrant.

The ending point can be simply understood as the symmetrical point of the starting point. These somewhat complex definitions lead to an interesting effect sometimes called magic corners : the corners nearest to the starting and ending points have the same color as their respective starting or ending points.

By adding more color-stop points on the gradient line, you can create a highly customized transition between multiple colors. A color-stop's position can be explicitly defined by using a CSS data type represents a distance value. Lengths can be used in numerous CSS properties, such as width, height, margin, padding, border-width, font-size, and text-shadow.

It is often used to define a size as relative to an element's parent object. Numerous properties can use percentages, such as width, height, margin, padding, and font-size. If you don't specify the location of a color, it is placed halfway between the one that precedes it and the one that follows it. The following two gradients are equivalent. By default, colors transition smoothly from the color at one color stop to the color at the subsequent color stop, with the midpoint between the colors being the half way point between the color transition.

If two or more color stops are at the same location, the transition will be a hard line between the first and last colors declared at that location. Color stops should be listed in ascending order. Subsequent color stops of lower value will override the value of the previous color stop creating a hard transition. Multi-position color stop are allowed. A color can be declared as two adjacent color stops by including both positions in the CSS declaration.

The following three gradients are equivalent:.Learn more and introduce yourself.

Elements with angled horizontal edges can create a unique visual flow while progressing through a page. Though not commonly seen on the web, we decided to use the treatment on the new website for The National Trust for Historic Preservation. Example 1: Image with bottom angle and solid color block with top reversed angle.

CSS transforms are commonly used to achieve angled edges by skewing a parent element and then unskewing a child element, but this technique is limited to parallel edges. What if you need to apply the effect in different ways — only to one edge, to both top and bottom edges but with reversed angles, or to an image element? Fortunately, there are a few other options.

Angled Edges with CSS Masks and Transforms

The first, and easiest option, is to use CSS clip-path. We chose to use this technique on large hero images. This assigns a clipping region to the image and essentially hides the bottom edge at a slight angle. We also used CSS clip-path on blocks with background images. Unlike the hero image above, the height of this block is variable across breakpoints. In order to maintain the correct angle not too steep across viewports, pixel values had to be used for any x coordinates.

The only downside to CSS based clip-paths is browser support. Firefox supports them, but only when using url. The second option is to use skewed generated content. This technique works great on blocks with solid color backgrounds. This adds a pseudo element at the bottom of the block, changes its point of rotation to the bottom right corner, and rotates it This technique has great browser support, and because of the background: inherit declaration, it works very well with inline background colors think admin assigned colors.

For more flexibility, we created a clever SASS mixin that allowed us to add angled edges to the top or bottom or both edges of a block, as well as reversing the rotation points. And there you have it!

I am wondering if there is any way to create this shape with pure CSS. To extend this problem further, this shape needs to clip the image inside think of it as a mask - but the grey border has to be visible. It's a little difficult keeping the border, but I managed to achieve a close effect using :before and :after elements with a parent container :before and :after don't work on an img tag.

You can do this by using pseudo, along with border-width and border-color see the below code to see how it can be done. Another Solution using this jQuery script for cross browser support. The exact shape can be achieved using CSS.

The idea is to have an element with a border-radius for the top-left corner, skew it along the Y axis and then position it just before the rectangle. Doing these would make it look as though the rectangular element has a triangular cut at the top with one curved edge. If the inside part of the shape has only a color solid or transparent then it can be achieved using only one element. However, if an image needs to be added inside the shape like mentioned in questionthen we need more than one element because we have to reverse the skew effect on the image and this cannot be done without a child element.

Alternately the same can be achieved in a more hassle free way with SVG like in the below snippet. It is possible to do this, but it is a CSS3 solution so won't work on older browsers I don't think. What I've done is, I've created two divs, one has a border all around, and the other has a border only on the bottom.

Using translate I've then rotated that div 45 degrees to mask the corner of the other div, giving the desired effect. Learn more. Is it possible to create an angled corner in CSS? Ask Question.

Recently, I wanted to add a little bit of character to a simple text container and decided to try folding over one of the corners.

With the help of an image, this is a pretty easy task. The method that I came up with is surely not innovative, but I thought it was interesting enough to share here. Basically, what we need, in addition to a rectangular box, is two triangles. Pretty easy! Now that we have a plan in place, we can begin building our shapes using CSS.

Non-Rectangular Header Using CSS Polygon - CSS Skewed Header

To get started, create a div like the one shown below. I started by giving the background a nice dark color, then moved on to styling the actual page class. Give it a width, height and margin, and assign white to the background color. As an optional step, I included a very subtle background gradient. Embedding this is as easy as copying and pasting the code given to you on the page in that link. Finally, to finish off the text, I added some padding to the paragraph, set its font and made brought its color a few shades back from black to help set it off from the headline.

At this point, you should have a nice little page something like the one shown below. Before we proceed, we have to learn to make a triangle with CSS.

Now set both the height and width to zero but apply a really thick border to the bottom and the left sides use two different colors. Each border corresponds to one of the triangles that result. Now watch what happens if we turn one of those borders transparent:. There you have it, a triangle made with pure CSS. We can even tweak the direction of the triangle by applying borders to different sides:.

Make sure that you set the transparent border to the direction that you want the hypotenuse to be facing. So if you want it to face right, make the right border transparent.

The reverse is true for the other borders. If you want the hypotenuse to face down, set the top border. If you want it to face up, set the bottom border. Check out this Tinkerbin to see an example of all four options at work. To do this, we need to follow three steps.
