Here, we implement a Price Range Slider using HTML, CSS, and JavaScript. Users can select their desired price range by moving the slider or by manually entering minimum and maximum values. JavaScript is used to synchronize inputs and add interactivity.
- HTML structures the slider and input fields.
- CSS styles the slider for a clean, user-friendly UI.
- JavaScript handles price updates and user interactions.
Preview
Prerequisites: HTML, CSS, JavaScript
Approach
- Create the structure of this project using HTML tags, like <div>, <h2> for the heading, <p> to display the Instructions, HTML input tags to enter a required range, and also give a Class name to each div.
- Style the structure with CSS using classes and elements.
- In JavaScript, Select the price range slider element using the document method querySelector().
- Add eventListeners to price and range input elements.
- Handle price input changes: Update slider and input values based on conditions.
- Handle range input changes: Adjust input values to meet the price gap or update price input values and slider positions.
