To make a Responsive web design is a very critical job. Because there are many devices and their screen size exists. A good responsive design works well on all screen sizes and resolutions. Thanks to bootstrap which make our job much easier with its grid layouts. Making a responsive design only with css and not using additional JavaScript is another important issue.
In this tutorial I am making a three column posts gallery with images fit according to height and width of the responsive view port. I am also using a svg image as frame in front of the post image to make a beautiful frame illusion of the post image. So lets start making it. After this tutorial I shall provide all source files to download for your projects.
First we make a file index.html and link bootstrap-4 css and js files to the template. and then write following html structure in it.
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0, shrink-to-fit=no"> <title>blue-post-gallery-2</title> <link rel="stylesheet" href="assets/bootstrap/css/bootstrap.min.css"> <link rel="stylesheet" href="assets/css/Features-Boxed.css"> </head> <body> <div class="features-boxed"> <div class="container"> <div class="row justify-content-center features"> <div class="col-lg-4 item"> <div class="box"> <div class="post-image-wrapper"> <div class="post-image-container"> <div class="post-image-holder"><img src="assets/img/truck.jpg"></div> <div class="post-background-img"></div> </div> </div> <h3 class="name">Works everywhere</h3> <p class="description">Aenean tortor est, vulputate quis leo in, vehicula rhoncus lacus.
