Streamlining Form Styles With CSS accent-color
Published: 2024-01-09 22:56:31


When using online applications on different platforms, web browsers may display default styles for HTML components, such as form controls, which can lead to slight differences in colors and fonts. To ensure a consistent and unified aesthetic, CSS can be used to customize specific form controls. 

Now, with the [`accent-color`](https://developer.mozilla.org/en-US/docs/Web/CSS/accent-color) property in CSS, developers can easily match the theme of their web application to the appearance of form controls. This allows for a consistent look and user experience across various browsers and platforms.

This article explores the `accent-color` property and how it simplifies the process of styling form controls.

## Understanding CSS accent-color
The CSS `accent-color` is a recent CSS property that's part of the Basic User Interface Module Level 4 specification. Its purpose is to provide web developers with a simple and consistent method of modifying the theme colors of different interactive components and form controls on a website.

```css=
/* Example of using the accent-color property with a definite color */
button,
input[type="text"],
select {
  accent-color: #ff5733; /* Replace with your desired accent color */
}
```
To maintain a consistent accent color in the web application, we utilize the `accent-color` attribute in the code example above for buttons, text input fields, and select boxes.

*However, it's important to note that the `accent-color` property itself doesn't create standalone output. It needs to be applied to specific HTML elements to see its effect visually.*

Checkboxes, radio buttons, range sliders, and input fields are known to be challenging to style. In the past, developers had to resort to complex workarounds and customized CSS to achieve a consistent look that aligned with their web application's overall design. Fortunately, CSS `accent-color` simplifies this process by enabling developers to choose a single accent color that matches their design scheme. This makes it easier to create visually appealing and consistent user interfaces.

By using `accent-color` in form styles, developers can achieve the following objectives:

1. Consistency: Ensure that form controls across different browsers and platforms have a uniform appearance by defining a consistent accent color.
2. Accessibility: Improve the accessibility of web forms by ensuring that the accent color meets contrast and visibility requirements, making them more user-friendly for all users, including those with disabilities.
3. Efficiency: Streamline the styling process for form controls, reducing the need for complex and time-consuming CSS workarounds.

## Common Syntax and Values in accent-color
You can set the accent color of form controls and interactive elements on your web app by using the `accent-color` attribute, which accepts three value types:

1. **`auto`**: This value instructs the browser to use the accent color specified in the user's system or web browser settings as the accent color, ensuring that your online forms match the user's chosen color scheme.
2. Color Values: Accent color can be defined in various color formats, such as:
- Color Constants: You can use named color constants like hotpink, which represent specific colors.
- HEX Values: HEX values like #00ff00 provide precise control over the RGB color channels.
- Color Functions: You can use color functions like rgb(20, 25, 100) or hsl(35, 100%, 50%) to define the accent color based on RGB or HSL color models.

3. Global Values: Global values like `inherit` and `initial` supported by CSS can set `accent-color` to default or inherit from parent element.

Here's a practical demonstration of using these values in CSS:
```css=
/* Using 'auto' to respect user preferences */
.selector-auto {
  accent-color: auto;
}

/* Using a named color constant */
.selector-hotpink {
  accent-color: hotpink;
}

/* Using a HEX value for precise color control */
.selector-green {
  accent-color: #00ff00;
}

/* Using an RGB color function */
.selector-rgb {
  accent-color: rgb(20, 25, 100);
}

/* Using an HSL color function */
.selector-hsl {
  accent-color: hsl(35, 100%, 50%);
}
```

## Leveraging CSS accent-color for Form Inputs
Now that we understand the basics, let's explore how to use CSS `accent-color` to improve form designs.

### Applying accent-color to Input Elements
To get started, apply the `accent-color` to form input elements. This ensures that text fields and other input elements align with your overall design theme.
```css
input,
textarea,
select {
  accent-color: <your-color>;
}
```
Replace ``<your-color>`` with the desired color, which can be a named color, hexadecimal code, RGB, or any valid CSS color representation.

By applying `accent-color` to these input elements, you ensure that they inherit the user's chosen accent color, creating a consistent and visually pleasing look. A detailed example and overview of `accent-color` being added to form input elements like Text fields, Buttons, and checkboxes will be reviewed in this article.

### Customizing Radio Buttons, Range Sliders, and Checkboxes with accent-color
While `accent-color` provides a straightforward way to harmonize form elements with the user's preferences, you can still customize the appearance further to match your website's design. You can modify the following aspects:

**Radio Buttons**

When creating a form with radio buttons, it's important to consider how they look and function.

One way to improve the design of radio buttons is by using the `accent-color` CSS property. This can improve the user's experience, maintain consistency with branding, and provide visual highlighting.

To decorate radio buttons using the `accent-color` property, simply apply the property to the input element and watch as the button takes on a new and improved look. 

By implementing this simple tip shared below, you can create a more polished and professional form that users will appreciate.

First we write out our HTML code:
```htmlembedded=
<div class="note">Select an Hobby:</div>
<div class="inline-item">
  <input type="radio" id="opt1" name="mainhobby" />
  <label for="opt1">Eating</label>
</div>
<div class="inline-item">
  <input type="radio" id="opt2" name="mainhobby" />
  <label for="opt2">Sleeping</label>
</div>
<div class="inline-item">
  <input type="radio" id="opt3" name="mainhobby" />
  <label for="opt3">Coding</label>
</div>
```
The Result:


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/dffqiqs4uc9jpd0djagt.png)



This HTML code generates a simple form that allows users to choose from three hobbies: "Eating," "Sleeping," and "Coding." Each hobby has its own radio button, contained within a container with the class "inline-item." Since all the radio buttons have the same `name`, "mainhobby," only one option can be selected at a time. There are `label` components associated with each option, making it easy for users to choose their preferred hobby by clicking on the `label`. The "note" section at the beginning provides brief instructions, prompting users to select a hobby from the list of options.

For the styling of the HTML code above with the `accent-color` property, check out the css code below:
```css=
input[type="radio"] {
  accent-color: red;
  width: 20px;
  height: 20px;
  margin: 3px;
}
```
The CSS code above targets radio input elements and modifies their appearance. It changes the color of the radio buttons to red using the `accent-color` property.

Our result:

**Range Sliders**

Range sliders are key components of user interfaces that can be found in a wide variety of applications, from audio volume controls to data filtering tools. Despite being frequently overlooked, they are incredibly helpful. They allow users to precisely adjust data or settings, and their intuitive nature improves the overall user experience in modern web design. When it comes to consistency, branding, user guidance, and aesthetics, among other things, the `accent-color` CSS property can play a critical role in customizing range sliders. By including the `accent-color` attribute in your range slider styling toolkit, you can not only make your UI elements look more attractive but also make it easier to convey meaning and interactivity.


To illustrate this point, let's take a look at an example of how to decorate a range slider with `accent-color`.

```hmtl=
<input type="range" style="width: 300px; accent-color:green"/>
```
You should get the result below:


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ntlsvqg6xap9m0414laq.gif)

Utilizing the `accent-color` property with your sliders can greatly improve the visual appeal of your webpage. In this instance, the color is set to green, and the slider width is adjusted to 300 pixels. This is a clever approach to make your sliders more attractive and user-friendly.

**Checkboxes**

An example of HTML and CSS code is provided below to demonstrate how changing checkboxes can transform your web forms from ordinary to visually appealing and functional:
```htmlembedded=
<div class="custom-checkbox">
  <input type="checkbox" id="agree" name="agree" />
  <label for="agree">I agree to the terms and conditions</label>
  <div class="checkmark"></div>
</div>
```
The Result:


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/tuhc89ti39z3kjo8rqmb.png)



In this code, there is a personalized checkbox that comprises an input element with the type "checkbox." The checkbox label reads "I agree to the terms and conditions." To make the checkbox more visually engaging and user-friendly in web forms, a div encloses a visual "checkmark." This customization enhances the design of the checkboxes, making them more appealing to users.

Now for the CSS code:
```css=
input[type="checkbox"] {
  accent-color: red;
  width: 20px;
  height: 20px;
}
```
And for the result of our code:


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/bpjpbpltuv7tnqhtz4mw.gif)

 The CSS code above utilizes the `accent-color` property to change the color of the checkboxes to red. Additionally, the width and height are adjusted to 20 pixels, which makes the checkboxes larger and more visually distinctive. These style modifications help improve the user experience of a webpage, making it easier for users to interact with checkboxes.

Customizing these elements allows you to maintain a consistent visual identity while ensuring that your forms are in sync with the user's color preferences.

### Addressing Common Challenges and Issues with CSS accent-color
* Limited Customization: `accent-color` is primarily intended for harmonizing with the user's system preferences. It may not provide the level of customization some designers desire.

* Browser Support: As mentioned earlier, browser support may vary. You may need to provide alternative styles for older browsers or unsupported environments.

* Accessibility: Ensure that your custom styles, when combined with `accent-color`, maintain good contrast and accessibility standards.
