Question

I’d like to edit the forms CSS of bootstrap.

bootstrap-sass / vendor / assets / stylesheets / bootstrap / _forms.scss 

I grabbed..

textarea,
input[type="text"],
input[type="password"],
input[type="datetime"],
input[type="datetime-local"],
input[type="date"],
input[type="month"],
input[type="time"],
input[type="week"],
input[type="number"],
input[type="email"],
input[type="url"],
input[type="search"],
input[type="tel"],
input[type="color"],
.uneditable-input {
  background-color: $inputBackground;
  border: 1px solid $inputBorder;
  @include box-shadow(inset 0 1px 1px rgba(0,0,0,.075));
  @include transition(border linear .2s, box-shadow linear .2s);

  // Focus state
  &:focus {
    border-color: rgba(82,168,236,.8);
    outline: 0;
    outline: thin dotted \9; /* IE6-9 */
    @include box-shadow(inset 0 1px 1px rgba(0,0,0,.075), 0 0 8px rgba(82,168,236,.6));
  }
}

And I attempted to change the rgba values of the focus state.

@include box-shadow(inset 0 1px 1px rgba(0,0,0,.075), 0 0 8px rgba(200,168,136,.6)

But then I get the following error:
Mixin transition takes 1 argument but 2 were passed.

I think I’m not allowed to just “override” the box-shadow mixin? But I’m not sure how to fix this issue. I appreciate any help.

Answer 1

you want to escape the argument :

@include box-shadow(~"inset 0 1px 1px rgba(0,0,0,.075), 0 0 8px rgba(200,168,136,.6)")

notice the ~ (tilde) and the " (quotation marks). This clears confusion about the comma, that less interprets as a seperation between two arguments. See the “escaping” part on less documentation for more info.
