Use AngularJS to create a custom form field directive that allows users to input a specific number of characters and displays a dynamic count of remaining characters as the user types. The directive should be styled to match the overall theme of the application and display an error message if the maximum character limit is exceeded.

Sure, I can provide you with a basic AngularJS directive based on your requirements. This directive creates a form field with a text input and displays the remaining characters to be typed as a tooltip. It also checks if the maximum character limit is exceeded and shows an error message if that happens. Here's how you might do it:

```angular
angular.module('myApp').directive('characterCounter', function() {
  return {
    restrict: 'EA',
    scope: {
      maxChars: '=',
      errorLabel: '@?',
      successLabel: '@?'
    },
    template: '<div><input type="text" ng-model="inputValue" ng-maxlength="maxChars" /><span ng-show="showTooltip">{{remainingChars}}</span></div>',
    link: function(scope, element, attr) {
      scope.remainingChars = scope.maxChars;
      scope.showTooltip = false;

      element.on('input', function() {
        var value = element[0].value;
        scope.inputValue = value;

        if (value.length > scope.maxChars) {
          scope.showTooltip = true;
          if (scope.errorLabel) {
            elem[0].classList.add(scope.errorLabel);
          }
        } else {
          scope.showTooltip = false;
          if (scope.successLabel) {
            elem[0].classList.add(scope.successLabel);
          }
        }

        scope.remainingChars = scope.maxChars - value.length;
      });
    }
  };
});
```

To use this directive, you would include it in your HTML and bind the maximum character count and error/success labels:

```html
<input character-counter max-chars="100" error-label="invalidChar" success-label="validChar" />
```

In this example, the input field will allow a maximum of 100 characters and display "invalidChar" if the limit is exceeded, while "validChar" will be displayed when the limit is not exceeded. You would define these labels in your CSS. For example:

```css
.invalidChar {
  color: red;
}

.validChar {
  color: green;
}
```

You can customize the color or any other relevant CSS styles in your application.

Use AngularJS to create a custom form field directive that allows users to input a specific number of characters and displays a dynamic count of remaining characters as the user types. The directive should be styled to match the overall theme of the application and display an error message if the maximum character limit is exceeded.

To create a custom form field directive in AngularJS that meets the given requirements, follow these steps:

1. Create an HTML file (index.html) with the following content:

```html
<!DOCTYPE html>
<html ng-app="myApp">
<head>
  <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"></script>
  <script src="app.js"></script>
  <link rel="stylesheet" href="styles.css">
</head>
<body>
  <form name="myForm">
    <custom-input max-length="10" name="myInput" ng-model="userInput"></custom-input>
    <p ng-if="myForm.myInput.$error.maxlength">Error: Maximum character limit exceeded!</p>
  </form>
</body>
</html>
```

2. Create a JavaScript file (app.js) with the following content:

```javascript
angular.module('myApp', [])
  .directive('customInput', function() {
    return {
      restrict: 'E',
      scope: {
        maxLength: '=',
        ngModel: '=',
        name: '@'
      },
      template: `
        <div class="custom-input-container">
          <input type="text"
                 ng-model="ngModel"
                 name="{{name}}"
                 ng-maxlength="maxLength"
                 required>
          <span class="character-count">({{maxLength - ngModel.length}} characters remaining)</span>
        </div>
      `
    };
  });
```

3. Create a CSS file (styles.css) with the following content to style the directive and match your application's theme:

```css
.custom-input-container {
  position: relative;
  display: inline-block;
  margin-bottom: 10px;
}

input[type="text"] {
  padding: 5px;
  font-size: 16px;
  border: 1px solid #ccc;
  border-radius: 4px;
}

.character-count {
  position: absolute;
  right: 10px;
  bottom: 6px;
  font-size: 12px;
  color: #888;
}
```

Now you have created a custom form field directive in AngularJS that allows users to input a specific number of characters and displays a dynamic count of remaining characters as they type. The directive is styled to match the overall theme of your application, and it displays an error message if the maximum character limit is exceeded.

To test this code, open the `index.html` file in a web browser. You should see the custom input field with character counting functionality and error handling for exceeding the maximum character limit.
