Dynamic inline styles in Svelte - Mini Project: Build & Apply

Dynamic inline styles

📖 Scenario: You are building a simple Svelte component that changes the color of a text dynamically based on a condition. This is useful for highlighting important messages or showing status updates in different colors.

🎯 Goal: Create a Svelte component that uses dynamic inline styles to change the text color based on a variable.

📋 What You'll Learn

Create a variable called color with the value 'blue'.

Create a variable called isImportant with the value true.

Use a dynamic inline style to set the text color to color only if isImportant is true.

Display a paragraph with the text 'This text changes color dynamically.' using the dynamic style.

💡 Why This Matters

🌍 Real World

Dynamic inline styles are used in web apps to highlight important information, show status changes, or customize appearance based on user actions.

💼 Career

Understanding how to apply dynamic styles in frameworks like Svelte is essential for frontend developers to create interactive and visually responsive user interfaces.

1

Set up initial variables

Create a variable called color and set it to the string 'blue'.

Svelte

// Your code here

Hint

Use let color = 'blue'; to create the variable.

2

Add a condition variable

Create a variable called isImportant and set it to true.

Svelte

let color = 'blue';
// Your code here

Hint

Use let isImportant = true; to create the condition variable.

3

Apply dynamic inline style

Add a paragraph element with the text 'This text changes color dynamically.' and use a dynamic inline style to set color only if isImportant is true. Use Svelte's style binding syntax: style="color: {isImportant ? color : 'black'}".

Svelte

let color = 'blue';
let isImportant = true;

Hint

Use a paragraph tag with style="color: {isImportant ? color : 'black'}" to apply the dynamic color.

4

Complete the component

Add the <script> tags around the variables and keep the paragraph outside to complete the Svelte component structure.

Svelte

let color = 'blue';
let isImportant = true;


This text changes color dynamically.

Hint

Wrap your variables inside <script> tags for Svelte to recognize them.
