How to style text

Creating styled text in Adobe XD is easy! In this tutorial, we'll show you how to create a text element with a specific color and font size, and also a text element with multiple inline colors.

Prerequisites#

Development Steps#

Info Complete code for this plugin can be found on GitHub.

1. Prepare your plugin scaffold#

First, edit the manifest file for the plugin you created in our Quick Start Tutorial.

Replace the uiEntryPoints field of the manifest with the following:

Copied to your clipboard
1"uiEntryPoints": [
2 {
3 "type": "menu",
4 "label": "Create Styled Text",
5 "commandId": "createStyledTextCommand"
6 }
7]

If you're curious about what each entry means, see the manifest documentation, where you can also learn about all manifest requirements for a plugin to be published in the XD Plugin Manager.

Then, update your main.js file, mapping the manifest's commandId to a handler function.

Replace the content of your main.js file with the following code:

Copied to your clipboard
1function createStyledTextHandlerFunction(selection) {
2 // The body of this function is added later
3}
4
5module.exports = {
6 commands: {
7 createStyledTextCommand: createStyledTextHandlerFunction,
8 },
9};

The remaining steps in this tutorial describe additional edits to the main.js file.

2. Require in XD API dependencies#

For this tutorial, we just need access to two XD scenegraph classes.

Add the following lines to the top of your main.js file:

Copied to your clipboard
1// Add this to the top of your main.js file
2const { Text, Color } = require("scenegraph");

Now the Text and Color classes are required in and ready to be used.

3. Create the main function#

In this step, we'll build out the main function, createStyledTextHandlerFunction, that we added in the first step. This function will add red text to the user's doucment.

Each of the numbered comments are explained below the code:

Copied to your clipboard
1function createStyledTextHandlerFunction(selection) {
2 const node = new Text(); // [1]
3 node.text = "This is some red text"; // [2]
4 node.fill = new Color("#FF0000"); // [3]
5 node.fontSize = 24;
6
7 selection.insertionParent.addChild(node); // [4]
8 node.moveInParentCoordinates(20, 50); // [5]
9}
  1. Create the Text object.
  2. Populate text with a string.
  3. Set the color to red and the font size to 24 for the entire string.
  4. Add text to the scenegraph as a child of the currrently-selected artboard.
  5. Move text to a different position relative to the artboard's coordinate system.

Character styles such as color and font size can also vary within the text. Read more below for details.

4. Test the plugin#

If you reload the plugin and run it, you should see the following result:

Red text

Not bad for a few lines of code! Let's push it a little further.

5. Update the main function#

All red is ok, but we can make our text more colorful than that. Let's change the code to apply different styles to different parts of the text, resulting in rainbow-colored text.

The styleRanges property lets us apply different styles to different ranges of the node's text:

Copied to your clipboard
1function createStyledTextHandlerFunction(selection) {
2 const node = new Text();
3
4 const textData = [
5 // [1]
6 { text: "This ", color: "red" },
7 { text: "is ", color: "orange" },
8 { text: "some ", color: "yellow" },
9 { text: "ra", color: "green" },
10 { text: "in", color: "blue" },
11 { text: "bow ", color: "indigo" },
12 { text: "text", color: "violet" },
13 ];
14
15 node.text = textData.map((item) => item.text).join(""); // [2]
16
17 node.styleRanges = textData.map((item) => ({
18 // [3]
19 length: item.text.length,
20 fill: new Color(item.color),
21 }));
22
23 node.fontSize = 24; // [4]
24
25 selection.insertionParent.addChild(node);
26 node.moveInParentCoordinates(20, 50);
27}

Here's what's changed:

  1. This data structure stores the text to be displayed, as well as the color to use for each fragment of text.
  2. Just as before, we set node.text equal to the text to be displayed. This time, the text string is created by concatenating together all the .text property values contained in the textData array. The Array#map gets us an array of strings, which we combine into a single string with Array#join.
  3. In this step, we build an array of style objects, applying each style to a few characters of the text string. We use Array#map again, this time converting each item in the textData array into a style object. The length of each style is equal to the length of the text string contained in one element of the textData array. The fill of each style uses the color value contained in one element of the textData array.
  4. We can still apply styles to the entire text node at once, as in the earlier example. Here, the font size will be set to the same value across all the style ranges we just created.

tip The Color constructor understands some color names, but you have plenty of other options for defining colors precisely, including hex, rgba, and more. See the Color reference for more information.

Here are a few things to notice about the styleRanges property of Text objects:

  • styleRanges is an array of objects; you can have more than one style for a text node.
  • Each range is given a length which determines the number of characters to which the style is applied, starting from the end of the previous style range.
  • Character styles such as fill or fontSize can be set to different values in each style range, or they can be set on the Text node overall to apply the setting to all existing style ranges.

6. Run the plugin#

After saving all of your changes, reload the plugin in XD and run it. You'll now have rainbow-colored text:
