Customizing React-Calendar-Timeline: Changing Header Text Colors
React-Calendar-Timeline is a powerful library for creating interactive timelines in your React applications. Its default styling provides a clean and functional look, but sometimes you might want to customize it further to match your project's design. One common customization is changing the color of the text on the header, which can be easily achieved with some CSS styling.
The Scenario and Original Code
Let's say we have a basic React-Calendar-Timeline component like this:
import React from 'react';
import { Calendar, Timeline } from 'react-calendar-timeline';
const MyTimeline = () => {
return (
<Calendar
groups={[
{ id: 1, title: 'Group 1' },
{ id: 2, title: 'Group 2' },
]}
items={[
{ id: 1, group: 1, title: 'Item 1', start_time: new Date(2023, 10, 25), end_time: new Date(2023, 10, 25, 12) },
{ id: 2, group: 2, title: 'Item 2', start_time: new Date(2023, 10, 26, 10), end_time: new Date(2023, 10, 26, 16) },
]}
defaultTimeStart={new Date(2023, 10, 25)}
defaultTimeEnd={new Date(2023, 10, 26)}
>
<Timeline groups={[{ id: 1, title: 'Group 1' }, { id: 2, title: 'Group 2' }]} />
</Calendar>
);
};
export default MyTimeline;
This code will render a timeline with two groups, each displaying items. However, the header text (e.g., 'Group 1', 'Group 2') is in the default black color.
Customizing the Header Text Color
To change the header text color, we can use inline styles or create a separate CSS class.
1. Inline Styles:
import React from 'react';
import { Calendar, Timeline } from 'react-calendar-timeline';
const MyTimeline = () => {
return (
<Calendar
groups={[
{ id: 1, title: 'Group 1' },
{ id: 2, title: 'Group 2' },
]}
items={[
{ id: 1, group: 1, title: 'Item 1', start_time: new Date(2023, 10, 25), end_time: new Date(2023, 10, 25, 12) },
{ id: 2, group: 2, title: 'Item 2', start_time: new Date(2023, 10, 26, 10), end_time: new Date(2023, 10, 26, 16) },
]}
defaultTimeStart={new Date(2023, 10, 25)}
defaultTimeEnd={new Date(2023, 10, 26)}
>
<Timeline
groups={[{ id: 1, title: 'Group 1' }, { id: 2, title: 'Group 2' }]}
groupStyle={{
title: {
color: 'blue' // Set header text to blue color
}
}}
/>
</Calendar>
);
};
export default MyTimeline;
2. Separate CSS Class:
import React from 'react';
import { Calendar, Timeline } from 'react-calendar-timeline';
import './MyTimeline.css'; // Import CSS file
const MyTimeline = () => {
return (
<Calendar
groups={[
{ id: 1, title: 'Group 1' },
{ id: 2, title: 'Group 2' },
]}
items={[
{ id: 1, group: 1, title: 'Item 1', start_time: new Date(2023, 10, 25), end_time: new Date(2023, 10, 25, 12) },
{ id: 2, group: 2, title: 'Item 2', start_time: new Date(2023, 10, 26, 10), end_time: new Date(2023, 10, 26, 16) },
]}
defaultTimeStart={new Date(2023, 10, 25)}
defaultTimeEnd={new Date(2023, 10, 26)}
>
<Timeline
groups={[{ id: 1, title: 'Group 1' }, { id: 2, title: 'Group 2' }]}
groupStyle={{ title: { className: 'group-title' } }} // Apply CSS class
/>
</Calendar>
);
};
export default MyTimeline;
MyTimeline.css:
.group-title {
color: red; /* Set header text to red color */
}
Both approaches achieve the same result: changing the header text color to your desired color. Choose the method that best suits your project's structure and preferences.
Additional Tips
- Remember to use a valid CSS color value for the
colorproperty, such as hex codes, RGB values, or named colors. - You can also apply other CSS properties to further customize the appearance of the header, such as font size, font weight, and text alignment.
- For more complex styling, consider using a CSS preprocessor like Sass or Less to organize your styles and enhance maintainability.
By following these steps and applying some CSS styling, you can easily customize the header text color in your React-Calendar-Timeline component and create a visually appealing and functional timeline.
