Use the "border-radius" CSS property to add rounded corners to elements

Web pages are built from boxes and each box has its own border with you are able to style using CSS border properties. At first look, it looks easy. Using CSS border you can set border style and the border width, even round the box corners. But this is only the beginning. There is more information that you need to know if you want to manage a web view. In this post, I wrote about several useful things about CSS border and box calculations.

We are living in an era when each pixel count. UX and UI are used to build a competitive advantage by means that every single pixel on web site matters. If so, you need to know how web browsers count spaces that each box takes on the web page.

For example, when you set a text box that will have px width and add to this box the CSS border witch width will be set on 1 px finally your text box will occupy px. As I mentioned before these 2 px counts. Below I paste an image, that shows how web browsers count box size.

Now you can add all this value: text width, padding width, border width, and margin width to keep the idea of pixel-perfect web page building, or there is the simplest way to keep box sizing in the control.

You can use CSS properties called box-sizing. It has two options:. As you see this is a very important CSS value when you want to build pixel-perfect web pages.

Just add which part of the border should be styled, and you get it. You can also set different colors or border width for each parts of CSS border using description like this: border-width: 1px 2px 1px 2px. Like in all CSS properties writing in this way, properties are related to the following peace of border: top, right, bottom, left.

You can also achieve an even better effect by setting different border-radius in each half of the edge. When you set CSS properties like these:. Then left half of the edge will be radius by 20px and the right site will be radius by 30px.

This allows you to build interesting shapes. But what if you like to cut straight one of the corners? But it is available when you use some tricks to do that. The first trick is that you will use ::before pseudo-element to build a roof of the box, and then you will be able to made a sharpie cut in the edge. All magic behind the scene relies on made border-right or left transparent. Using these properties you are able to cut the edges as you like.

You can build several different shapes using these properties. The last trick you can use to achieve similar effects relies on background properties named linear-gradient. Just like the properties above allows you to cut edges of the background.

And also have these same disadvantages that disable the border option, because the border will wrap the whole box. As you can see you can use these effects using different CSS properties. Your email address will not be published. Search Title.
