A portfolio gallery is ideal for websites with diverse or extensive content. It allows you to showcase all content on the front page in an organized manner. By adding filters, users can easily find specific content they are interested in.
Approach
- The HTML defines the structure, including a container for the title, buttons for filtering different categories, and a gallery grid for portfolio items grouped by categories like Markup, Style, and Scripting.
- The CSS styles the page elements, setting dimensions, colors, and layout properties. It includes responsive design adjustments to ensure the gallery adapts to various screen sizes, with columns changing width at different breakpoints.
- Buttons are assigned classes and click events to filter portfolio items. The
geeksportalfunction shows or hides items based on the category selected. - The
geeksportalfunction filters items by adding or removing the "show" class to elements based on their category. - JavaScript adds an event listener to each button to highlight the currently active filter button by adding the "active" class.
Example: The example shows how to add filter with Portfolio Gallery using HTML, CSS and JavaScript.
