How to change border color of textarea on :focus

Question

.input:focus {
    outline: none !important;
    border:1px solid red;
    box-shadow: 0 0 10px #719ECE;
  }

There is an input:focus as there is a textarea:focus

    input:focus { 
        outline: none !important;
        border-color: #719ECE;
        box-shadow: 0 0 10px #719ECE;
    }
    textarea:focus { 
        outline: none !important;
        border-color: #719ECE;
        box-shadow: 0 0 10px #719ECE;
    }

Probably a more appropriate way of changing outline color is using the outline-color CSS rule.

textarea {
  outline-color: #719ECE;
}

or for input

input {
  outline-color: #719ECE;
}

box-shadow isn't quite the same thing and it may look different than the outline, especially if you apply custom styling to your element.

so simple :

 outline-color : green!important;

the whole CSS for my react-boostrap button is:

 .custom-btn {
     font-size:1.9em;
     background: #2f5bff;
     border: 2px solid #78e4ff;
     border-radius: 3px;
     padding: 50px 70px;
     outline-color : blue !important;
     text-transform: uppercase;
     user-select: auto;
     -moz-box-shadow: inset 0 0 4px rgba(0,0,0,0.2);
     -webkit-box-shadow: inset 0 0 4px rgba(0, 0, 0, 0.2);
     -webkit-border-radius: 3px;
     -moz-border-radius: 3px;
 }

Try out this probably it will work

input{
outline-color: #fff //your color
outline-style: none // it depend on you 
}

you need just in scss varible

$input-btn-focus-width:       .05rem !default;

You can use CSS's pseudo-class to do that. A pseudo-class is used to define a special state of an element.

there is a ::focus pseudo-class that is used to select the element that has focus. So you can hook it in your CSS like this

Using class

.my-input::focus {
  outline-color: green;
}

Using Id

#my-input::focus {
  outline-color: red;
}

Directly selecting element

input::focus {
  outline-color: blue;
}

Using attribute selector

input[type="text"]::focus {
  outline-color: orange;
}
