Changing the color of an hr element

I think you should use border-color instead of color, if your intention is to change the color of the line produced by <hr> tag.

Although, it has been pointed in comments that, if you change the size of your line, border will still be as wide as you specified in styles, and line will be filled with the default color (which is not a desired effect most of the time). So it seems like in this case you would also need to specify background-color (as @Ibu suggested in his answer).

HTML 5 Boilerplate project in its default stylesheet specifies the following rule:

hr { display: block; height: 1px;
    border: 0; border-top: 1px solid #ccc;
    margin: 1em 0; padding: 0; }

An article titled “12 Little-Known CSS Facts”, published recently by SitePoint, mentions that <hr> can set its border-color to its parent's color if you specify hr { border-color: inherit }.

border-color works in Chrome and Safari.

background-color works in Firefox and Opera.

color works in IE7+.

---

I think this can be useful. this was simple CSS selector.

hr { background-color: red; height: 1px; border: 0; }

---

---

hr {
    height: 1px;
    color: #123455;
    background-color: #123455;
    border: none;
}

Doing it this way allows you to change the height if needed. Good luck. Source: How To Style HR with CSS

Tested in Firefox, Opera, Internet Explorer, Chrome and Safari.

hr {
    border-top: 1px solid red;
}

See the Fiddle.

This will keep the Horizontal Rule 1px thick while also changing the color of it:

hr {
  height: 0; 
  border: 0; 
  border-top: 1px solid #083972; 
}

---

Only border-top with color is enough to make the line in different color.

hr { border-top: 1px solid #ccc; }

---

---

hr {
  color: #f00;
  background-color: #f00;
  height: 5px;
}

---

I believe this is the most effective approach:

<hr style="border-top: 1px solid #ccc; background: transparent;">

Or if you prefer doing it on all hr elements write this on you CSS:

hr {
  background-color: transparent;
  border-top: 1px solid #ccc;
}

---

hr {
  background-color: #123455;
}

The background is the one you should try to change.

You can also work with the borders color. I am not sure; I think there are cross-browser issues with this. You should test it in different browsers.

After reading all the answers here, and seeing the complexity described, I set upon a small diversion for experimenting with HR. And, the conclusion is that you can throw out most of the monkeypatched CSS you wrote, read this small primer and just use these two lines of pure CSS:

hr {
  border-style: solid;
  border-color: cornflowerblue; /* or whatever */
}

That is ALL you need to style your HRs.

Works cross-browser, cross-device, cross-os, cross-english-channel, cross-ages.

No "I think this will work...", "you need to keep Safari/IE in mind...", etc.

no extra css - no height, width, background-color, color, etc. involved.

Just bulletproof colourful HRs. It's that simpleTM.

Bonus: To give the HR some height H, just set the border-width as H/2.

---

You can add bootstrap bg class like

<hr class="bg-light" />

---

if u use css class then it will be taken by all 'hr' tags , but if u want for a particular 'hr' use the below code i.e, inline css

<hr style="color:#99CC99" />

if it's not working in chrome try below code:

<hr color="red" />

---

Some browsers use the color attribute and some use the background-color attribute. To be safe:

hr {
  color: #color;
  background-color: #color;
}

---

It's simple and my favorite.

<hr style="background-color: #dd3333" />

---

I'm testing on IE, Firefox and Chrome May 2015 and this works best with the current versions. It centers the HR and makes it 70% wide:

hr.light { width:70%; margin:0 auto; border:0px none white; border-top:1px solid lightgrey; }

---

---

You should set border-width to 0; It works well in Firefox and Chrome.

hr { clear: both; color: red; background-color: red; height: 1px; border-width: 0; }

---

This is a test

Since i don't have reputation to comment, i will give here a few ideas.

if you want a css variable height, take off all borders and give a background color.

    hr{
        height:2px;
        border:0px;
        background:green;
        margin:0px;/*sometimes useful*/
    }
    /*Doesn't work in ie7 and below and in Quirks Mode*/

if you want simply a style that you know that will work (example: to replace a border in a ::before element for most email clients or

    hr{
        height:0px;
        border:0px;
        border-top:2px solid blue;
        margin:0px;/*useful sometimes*/
    }

In both ways, if you set a width, it will always have it's size.

No need to set display:block; for this.

To be totally safe, you can mix both, 'cause some browsers can get confused with height:0px;:

    hr{
        height:1px;
        border:0px;
        background:blue;
        border-top:1px solid blue;
        margin:0px;/*useful sometimes*/
    }

With this method you can be sure that it will have at least 2px in height.

It's a line more, but safety is safety.

This is the method you should use to be compatible with almost everything.

Remember: Gmail only detects inline css and some email clients may not support backgrounds or borders. If one fails, you will still have a 1px line. Better than nothing.

In the worst cases, you can try to add color:blue;.

In the worst of the worst cases, you can try to use a <font color="blue"></font> tag and put your precious <hr/> tag inside it. It will inherit the <font></font> tag color.

With this method, you WILL want to do like this: <hr width="50" align="left"/>.

Example:

    <span>
        awhieugfrafgtgtfhjjygfjyjg
        <font color="#42B3E5"><hr width="50" align="left"/></font>
    </span>
    <!--Doesn't work in ie7 and below and in Quirks Mode-->

You can use CSS to make a line with a different color, example would be like that:

border-left: 1px solid rgb(216, 216, 216);
border-right: medium none;
border-width: medium medium medium 2px;
border-style: none none none solid;
border-color: -moz-use-text-color -moz-use-text-color -moz-use-text-color rgb(216, 216, 216);

that code will display vertical grey line.

---

I like the answers setting border-top, but they are somehow still a little off in Chrome...
BUT if I set border-top: 1px solid black; and border-bottom: 0px; I end up with a truly single line (that also works fine with higher thickness).

---

Well, I am new in HTML, CSS and in Java but I tried my way which worked for me in all browsers. I have used JS instead of CSS which doesn't work with some browsers.

First of all I have given id="myHR" to HR element and used it in Java Script.
Here is the Code.

x = document.getElementById("myHR");
y = x.style.width = "600px";
y = x.style.color = "white";
y = x.style.height = "2px";
y = x.style.border = "none";
y = x.style.backgroundColor = "lightgrey";

Using font colours to modify horizontal rules makes them more flexible and easy to use.

The color property isn't inherited by default, so the following needs to be added to hr's to allow color inheritance:

/* allow hr to inherit color */ hr { border: 1px solid;} /* reusable colour modifier */ .fc_-alpha { color: crimson;} normal hr:

---

hr with colour modifier:

---

---

You could do this :

hr { border: 1px solid red; }

---

This s a test

---

---

You can give the <hr noshade> tag and go to your css file and add :

hr { border-top:0; color: #123455; }

---

This s a test

As a general rule, you can’t just set the color of a horizontal line with CSS like you would anything else. First of all, Internet Explorer needs the color in your CSS to read like this:

“color: #123455”

But Opera and Mozilla needs the color in your CSS to read like this:

“background-color: #123455”

So, you will need to add both options to your CSS.

Next, you will need to give the horizontal line some dimensions or it will default to the standard height, width and color set by your browser. Here is a sample code of what your CSS should look like to get the blue horizontal line.

hr {
border: 0;
width: 100%;
color: #123455;
background-color: #123455;
height: 5px;
}

Or you could just add the style to your HTML page directly when you insert a horizontal line, like this:

<hr style="background:#123455" />

Hope this helps.

I took a bet each way:

hr {
  border-top: 1px solid purple;
  border-color: purple;
  background-color: purple;
  color: purple;
}
