'How to change btn color in Bootstrap

Is there a way to change all .btn properties in Bootstrap? I have tried below ones, but still sometimes it shows the default blue color (say after clicking and removing the mouse etc). How can I change the entire theme altogether?

.btn-primary, .btn-primary:hover, .btn-primary:active, .btn-primary:visited {
    background-color: #8064A2;
}

The easiest way to see which properties you need to override is to take a look at Bootstrap's source code, specifically the .button-variant mixin defined in mixins/buttons.less. You still need to override quite a lot of properties to get rid of all of the .btn-primary styling (e.g. :focus, disabled, usage in dropdowns etc).

A better way might be to:

Create your own customized version of Bootstrap using Bootstrap's online customization tool
Manually create your own color class, e.g. .btn-whatever
Use a LESS compiler and use the .button-variant mixin to create your own color class, e.g. .btn-whatever

Solution 2:^[2]

If you want to override any default properties in Bootstrap you have to make the properties as important.

.btn-primary, .btn-primary:hover, .btn-primary:active, .btn-primary:visited {
    background-color: #8064A2 !important;
}

I hope this works for you.

2022 Update for Bootstrap 5

Bootstrap 5 has the same button-variant and button-outline-variant SASS mixins which can be used to customize the button color after bootstrap is imported...

/* import the Bootstrap */
@import "bootstrap";

/* ------- customize primary button color -------- */   
$mynewcolor:#77cccc;

.btn-primary {
    @include button-variant($mynewcolor, darken($mynewcolor, 7.5%), darken($mynewcolor, 10%), lighten($mynewcolor,5%), lighten($mynewcolor, 10%), darken($mynewcolor,30%));
}

.btn-outline-primary {
    @include button-outline-variant($mynewcolor, #222222, lighten($mynewcolor,5%), $mynewcolor);
}

2019 Update for Bootstrap 4

Now that Bootstrap 4 uses SASS, you can easily change the primary button color using the button-variant mixins:

$mynewcolor:#77cccc;

.btn-primary {
    @include button-variant($mynewcolor, darken($mynewcolor, 7.5%), darken($mynewcolor, 10%), lighten($mynewcolor,5%), lighten($mynewcolor, 10%), darken($mynewcolor,30%));
}
    
.btn-outline-primary {
    @include button-outline-variant($mynewcolor, #222222, lighten($mynewcolor,5%), $mynewcolor);
}

https://codeply.com/p/JnV3xDDiaH (SASS demo)

This SASS compiles into the following CSS...

.btn-primary {
    color: #212529;
    background-color: #7cc;
    border-color: #5bc2c2
}

.btn-primary:hover {
    color: #212529;
    background-color: #52bebe;
    border-color: #8ad3d3
}

.btn-primary:focus,
.btn-primary.focus {
    box-shadow: 0 0 0 .2rem rgba(91, 194, 194, 0.5)
}

.btn-primary.disabled,
.btn-primary:disabled {
    color: #212529;
    background-color: #7cc;
    border-color: #5bc2c2
}

.btn-primary:not(:disabled):not(.disabled):active,
.btn-primary:not(:disabled):not(.disabled).active,
.show>.btn-primary.dropdown-toggle {
    color: #212529;
    background-color: #9cdada;
    border-color: #2e7c7c
}

.btn-primary:not(:disabled):not(.disabled):active:focus,
.btn-primary:not(:disabled):not(.disabled).active:focus,
.show>.btn-primary.dropdown-toggle:focus {
    box-shadow: 0 0 0 .2rem rgba(91, 194, 194, 0.5)
}

.btn-outline-primary {
    color: #7cc;
    background-color: transparent;
    background-image: none;
    border-color: #7cc
}

.btn-outline-primary:hover {
    color: #222;
    background-color: #8ad3d3;
    border-color: #7cc
}

.btn-outline-primary:focus,
.btn-outline-primary.focus {
    box-shadow: 0 0 0 .2rem rgba(119, 204, 204, 0.5)
}

.btn-outline-primary.disabled,
.btn-outline-primary:disabled {
    color: #7cc;
    background-color: transparent
}

.btn-outline-primary:not(:disabled):not(.disabled):active,
.btn-outline-primary:not(:disabled):not(.disabled).active,
.show>.btn-outline-primary.dropdown-toggle {
    color: #212529;
    background-color: #8ad3d3;
    border-color: #7cc
}

.btn-outline-primary:not(:disabled):not(.disabled):active:focus,
.btn-outline-primary:not(:disabled):not(.disabled).active:focus,
.show>.btn-outline-primary.dropdown-toggle:focus {
    box-shadow: 0 0 0 .2rem rgba(119, 204, 204, 0.5)
}

To change the primary color for all classes see: Customizing Bootstrap CSS template and How to change the bootstrap primary color?

I guess you forgot .btn-primary:focus property and comma after .btn-primary

You also can use less and redefine some colors in variables.less file

With this in mind your code will be look like this:

.btn-primary,
.btn-primary:hover,
.btn-primary:active,
.btn-primary:visited,
.btn-primary:focus {
    background-color: #8064A2;
    border-color: #8064A2;
}

Just create your own button on:

add the CSS at the end off your boottrap.min.css

Cheers

Solution 6:^[6]

The simplest way is to:

intercept every button state
add !important to override the states

    .btn-primary:hover,
    .btn-primary:active,
    .btn-primary:visited,
    .btn-primary:focus {
      background-color: black !important;
      border-color: black !important;
    }

OR the more practical UI way is to make the hover state of the button darker than the original state. Just use the CSS snippet below:

.btn-primary {
  background-color: Blue !important;
  border-color: Blue !important;
}
.btn-primary:hover,
.btn-primary:active,
.btn-primary:visited,
.btn-primary:focus {
  background-color: DarkBlue !important;
  border-color: DarkBlue !important;
}

Solution 7:^[7]

Remove the button color class like "btn-success" and put a custom class like "btn-custom" and write css for that class. That simply works for me.

HTML :

<button class="btn btn-block login " type="submit">Sign In</button>

CSS:

 .login  {
    background-color: #0057fc;
    color: white;   
}

Solution 8:^[8]

You have missed one style ".btn-primary:active:focus" which causes that still during btn click default bootstrap color show up for a second. This works in my code:

.btn-primary, .btn-primary:hover, .btn-primary:active, .btn-primary:visited, .btn-primary:focus, .btn-primary:active:focus {
background-color: #8064A2;}

Solution 9:^[9]

Here's my flavor without the loss of hover. I personally like it better than the standard bootstrap transitioning.

.btn-primary,
.btn-primary:active,
.btn-primary:visited {
  background-color: #8064A2 !important;
}

.btn-primary:hover {
  background-color: #594671 !important;
  transition: all 1s ease;
  -webkit-transition: all 1s ease;
  -moz-transition: all 1s ease;
  -o-transition: all 1s ease;
  -ms-transition: all 1s ease;
}

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/css/bootstrap.min.css" rel="stylesheet" />
<button class="btn btn-primary">Hover me!</button>

I had run into the similar problem recently, and managed to fix it with adding classes

  body .btn-primary {
    background-color: #7bc143;
    border-color: #7bc143;
    color: #FFF; }
    body .btn-primary:hover, body .btn-primary:focus {
      border-color: #6fb03a;
      background-color: #6fb03a;
      color: #FFF; }
    body .btn-primary:active, body .btn-primary:visited, body .btn-primary:active:focus, body .btn-primary:active:hover {
      border-color: #639d34;
      background-color: #639d34;
      color: #FFF; }

Also pay attention to [disabled] and [disabled]:hover, if this class is used on input[type=submit]. Like this:

body .btn-primary[disabled], body .btn-primary[disabled]:hover {
  background-color: #7bc143;
  border-color: #7bc143; }

Adding a step-by-step guide to @Codeply-er's answer above for SASS/SCSS newbies like me.

Save btnCustom.scss.

/* import the necessary Bootstrap files */
@import 'bootstrap';

/* Define color */
$mynewcolor:#77cccc;

.btn-custom {
    @include button-variant($mynewcolor, darken($mynewcolor, 7.5%), darken($mynewcolor, 10%), lighten($mynewcolor,5%), lighten($mynewcolor, 10%), darken($mynewcolor,30%));
}

.btn-outline-custom {
    @include button-outline-variant($mynewcolor, #222222, lighten($mynewcolor,5%), $mynewcolor);
}

Download a SASS compiler such as Koala so that SCSS file above can be compiled to CSS.
Clone the Bootstrap github repo because the compiler needs the button-variant mixins somewhere.
Explicitly import bootstrap functions by creating a _bootstrap.scss file as below. This will allow the compiler to access the Bootstrap functions and variables.

@import "bootstrap/scss/functions";
@import "bootstrap/scss/variables";
@import "bootstrap/scss/mixins";
@import "bootstrap/scss/root";
@import "bootstrap/scss/reboot";
@import "bootstrap/scss/type";
@import "bootstrap/scss/images";
@import "bootstrap/scss/grid";
@import "bootstrap/scss/tables";
@import "bootstrap/scss/forms";
@import "bootstrap/scss/buttons";
@import "bootstrap/scss/utilities";

Compile btnCustom.scss with the previously downloaded compiler to css.

I think using !important is not a very wise option. It may cause for many other issues specially when making the site responsive. So, my understanding is that, the best way to do this to use custom button CSS class with .btn bootstrap class. .btn is the base style class for bootstrap button. So, keep that as the layout, we can change other styles using our custom css class. One more extra thing I want to mention here. Some people are trying to remove blue outline from the buttons. It's not a good idea because that accessibility issue when using keyboard. Change it's color using outline-color: instead.

I am not the OP of this answer but it helped me so:

I wanted to change the color of the next/previous buttons of the bootstrap carousel on my homepage.

Solution: Copy the selector names from bootstrap.css and move them to your own style.css (with your own prefrences..) :

.carousel-control-prev-icon,
.carousel-control-next-icon {
  height: 100px;
  width: 100px;
  outline: black;
  background-size: 100%, 100%;
  border-radius: 50%;
  border: 1px solid black;
  background-image: none;
}

.carousel-control-next-icon:after
{
  content: '>';
  font-size: 55px;
  color: red;
}

.carousel-control-prev-icon:after {
  content: '<';
  font-size: 55px;
  color: red;
}

Solution 14:^[14]

You can add custom colors using bootstrap theming in your config file for example variables.scss and make sure you import that file before bootstrap when compiling.

$theme-colors: (
    "whatever": #900
);

Now you can do .btn-whatever

Solution 15:^[15]

Here is my participation for the "outline" button:

Replace #8e5b5b with your color and #b3a7a7 by your color but usually more bright.

.btn-outline-custom{
  color: #8e5b5b;
  border-color: #8e5b5b;
}

.btn-outline-custom:focus{
  box-shadow: 0 0 0 0.2rem #b3a7a7;
  -webkit-box-shadow: 0 0 0 0.2rem #b3a7a7;
  outline: 0;
}

.btn-outline-custom:hover,
.btn-outline-custom:active{
  color: #fff;
    background-color: #8e5b5b;
    border-color: #8e5b5b;
}
