Responsive Filterable Image Gallery using HTML CSS & JavaScript

codingnepal profile image CodingNepal ・6 min read

Hey friends, today in this blog you'll learn how to create a Responsive Filterable Image Gallery using HTML CSS & JavaScript. In the earlier blog, I've shared how to create an Image Slider with Slider Controls in JavaScript and now it's time to create a Responsively Filterable Gallery.

A filterable image gallery means you can display as many images as you want. The most important feature of Filterable Image Gallery is that you will have the control to categorize all the pictures or images based on the specified parameter.

In this design [Responsive Filterable Image Gallery], there are a total of eight images on the webpage with the filter names navbar on the top. These images are specified to the different categories, when you click on the bag, there is only appear the bag related image, and when you click on the watch, there will appear watch related images only. Each image has a click event mean when you click on the particular image, that image will appear in a full image preview box with the category name and there is also a cross icon, so you can easily dismiss or close the preview box.

You can copy the codes from the given boxes or download the code files from the given link but I recommend you to download the source code files instead of copying codes because many things such as images, you won't get if you copy the codes. Click here to download code files.
