You will also learn how to use just CSS to add underlines to text and content. HTML has the hr tag to declare a thematic break for content. In older HTML specifications the HR tag was just a horizontal rule and did not provide the semantic meaning it does now.

Today it does not provide a visible break, but should be styled using CSS. This gives more control to the designer to make the HR tag match the site's theme. Since the beginning of HTML, or at least as far back as I can remember the U element has been a quick and dirty way to insert a horizontal line or horizontal rule to a web page. The U element is great because it can be used for the following scenarios:. Browsers draw a line across the entire width of the container, which can be the entire body or a child element.

Originally the HR element was styled using attributes. Today, with HTML5, the HR tag has become semantic, which means it tells the browser, assistive reading technology and other automated system there is a paragraph-level thematic break. This is a break in the content flow, but not a new page. It better serves as a visual queue of a change in topic.

For example, you could place them at the end of a section, before a new sub-header. Not only does this use the right system CSS to define rendering rules it allows you to reuse the same rule many times.

How to Make Horizontal Lines in HTML and CSS - Cool Ways You Can Style the HR Element

This makes your code more maintainable and your layouts more consistent. Browsers render the line by applying the styles to a combination of the background and border styles. The border is the primary style for the default line. Removing the border also removes the line. An invisible line can still be useful to provide the semantic information to the user agent without visual clutter that may interfere with the desired user experience.

You can control the line's width by setting the width property and then centering it using the following CSS rule. You can also adjust the line's thickness by setting the height value.

Color is set using the background-color property. As a bonus you can also use the opacity property to make the line semi-transparent.

The typical browser sets the margin to roughly half a character's width. But you can change this to any value you want.

This can add quality white space to your layouts and emphasize the content break. You can apply many different style variations to your horizontal lines. You are not limited to just color and width. Here I set the horizontal line's background style to an image of 5 yellow stars. I then made them repeat on the x-axis while centering the line. Pro-tip: set the background color to transparent so you don't accidentally show a color behind the image.

Adjusting the border size, color, and style will make the line look different and has the same effect in all modern browsers. For example, in this demonstration the border is red, dashed, and 1px wide:. A few weeks ago I published an article on making background stripes using CSS. Because you can apply those same background rules to a horizontal line you can do some pretty interesting things with the HR element. But first, let's look at a few simple CSS tricks. This first example changes the line's style to be a dashed line.

Now, apply one of the stripe techniques to the horizontal line. Here I use linear-gradients to make the affect.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

JacquesMarais, not sure that's necessary as it is a block element with no defined width so it would span the width of the entire container anyway.

It used represent a horizontal rule, but is now defined in semantic terms as a thematic break between content. Most browsers will still display it as a horizontal line unless told otherwise.

Squares and rectangles are easy, as they are the natural shapes of the web.

Add a width and height and you have the exact size rectangle you need. Add border-radius and you can round that shape, and enough of it you can turn those rectangles into circles and ovals. We also get the ::before and ::after pseudo elements in CSS, which give us the potential of two more shapes we can add to the original element. By getting clever with positioning, transforming, and many other tricks, we can make lots of shapes in CSS with only a single HTML element. Frontend Masters is the best place to get it.

Always so cool to see what shapes people make in CSS. I find myself looking back at these slides from Sara Soueidan from years back, where she even references what cool shapes folks had made with CSS, but might be better with SVG? That is the kind of easy peasy trick that is worth gold in pounds, please having in your bookmarks.

Hi, thanks for share, I just have a doubt, Can only solid colors be used for pentagons? I need a transparent pentagon only with the outline. Hey Oscar, good question! Yeah, the shape requires solid colors because it relies on border-color and it only accepts color values. That would allow you to draw the path and set a stroke on it without a fill on the shape itself. Curved Tail Arrow via Ando Razafimandimby.

Permalink to comment October 1, One of the requirements for my game Lexil were lines that connected the letters in each word.

At first I thought of using the canvas, however it turns out that drawing lines with CSS3's css transforms is quite simple, and has some nice benefits as well. Let's dive in and learn how you can use CSS transforms to draw a line between two points. Of course if you're impatient you can just skip to the demo. These include scaling, rotating, and skewing an element.

For instance, if you want to display a photo at a jaunty angle you could transform it with the following CSS:. The properties of an element's transform are the functions you want to apply scale, rotate, skew, etc.

With this simple concept in place you're half way to drawing your lines. By default transforms are applied assuming the origin is at the center, however when drawing lines you probably want to draw from one point to another, not expanding out from the center.


This is where the transform-origin comes into play. If you wanted to rotate an element around it's top left corner, you could set the transform-origin as follows:. The properties of transform-origin are the x and y position of the origin. Now for a quick bit of geometry, assuming we know the two points we want to draw a line between, all we need now is to figure out the angle to draw the line at, and the length of the line we want.

The length is easy, it's just the distance function, and the angle can be derived from the arc tangent of the x and y components of the line.

You'll probably be using JavaScript for this bit:. PIthis is so we can plug it into the CSS later. Since these lines are just DOM elements you can attach event listeners to them, style them with css, and use use CSS Transitions to animate them.

Ok, thanks for bearing with me, now that you know what is going on, take a look at the demo. For instance, if you want to display a photo at a jaunty angle you could transform it with the following CSS: Transforming an Image img. CSS Origin By default transforms are applied assuming the origin is at the center, however when drawing lines you probably want to draw from one point to another, not expanding out from the center. If you wanted to rotate an element around it's top left corner, you could set the transform-origin as follows: Transform Origins div.

A Geometry Refresher Now for a quick bit of geometry, assuming we know the two points we want to draw a line between, all we need now is to figure out the angle to draw the line at, and the length of the line we want. Putting It All Together We have all the pieces in place to draw lines now.Hi there, I'm Krasimir. Senior front-end engineer with over 13 years of experience. I writespeak and occasionally code stuff.

Follow KrasimirTsonev. By definition :before and :after are CSS pseudo elements. You can use them to insert something before or after the content of an element. There are some great articles giving the basics, but I wanted to write down a blog post for the real use cases.

Or, at least, to show what I'm using them for. Have in mind that you are actually adding an element before or after the content. It's not something which appear next to the selected element, but it is related to its content.

It is very popular to use :before or :after for displaying an icon. Because you are able to add every CSS style property, you could make the newly created element a block one and attach background image.

Krasimir Tsonev is developer who likes to write and tweet. We could add a small icon after that link indicating that it points to page outside the current domain. Usually when you do breadcrumbs you have links and separator between them. Instead of adding an element into the DOM you could achieve the same effect with pure css. There are few interesting things happening. Firstly, there is a bullet before all the links.

At the end I did the same thing to remove the separator from the last link in the list. I found this extremely helpful. Mainly because I don't have to take care about this in the code which generates the navigation. For example:. That's somehow wrong, because the PHP code should not be responsible for the look of the things. Using float property is still quite popular.

It helps a lot for layout organization. However, once an element is floated you need another element to clear the float. Otherwise the result is not so good. For example the following code:. Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec at purus ac lacus ultrices vehicula. The text should be below the links and instead of adding new DOM node you can use :before pseudo element to clear the float:.

Let's say that we have a smart thought and we want to format it.Horizontal line in HTML is not a hard concept to decode. How does it work? We are going to find the answer to that below. As we all know, to separate content we can go for horizontal lines.

We used attributes to style the HR element. Alternatively, in other words, it intimates the browser that there is a paragraph-level thematic break. The same information can be dispatched to an automated system or assistive reading technology. Here we get a break in the flow of the content instead of a new page. Alternatively, in other words, it lets you know about a change in topic.

For instance, you can introduce it at the end of a section. You may introduce it right before a fresh sub-header. We no longer use attributes for the same. The first advantage is that you use the right system to establish rendering rules. Moreover, it lets you reuse the rules as many times as you want.Usually, Graphs and Charts are mainly used for representing and organizing a set of numerical data with a graphical representation such as pie chart, line charts, bar graphs and many more.
