  1. Thank you for your answer.I attached the code again to the codepan.There are eight canvas, and if you change the location of the canvas and resize the window size, the location of the canvas returns to its place.How do I fix this phenomenon?Even if I resize, I want to make sure that the location of the canvas does not change. https://codepen.io/hongjunbae/pen/NWvjEMd
  2. Thank you for your quick response.I am studying a lot with the demo app you developed. Thank you. The 'resize' method was used to represent the demo app reactive.Every time 'resize' is performed, the x and y axes of the cell are changed and pushed.However, if you drag and swap the canvas, and 'resize', the locations of the canvas are rearranged in order.(red-blue-yellow-green-slategray-orange-purple-white -> resize -> red-orange-yellow-green-slategray-blue-purple-white) Even if the index of the cell is forcibly changed, it is arranged in place during resize.Even if you do "resize," how can you fix your location on the canvas? attach the code! <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1" /> <meta name="viewport" content="width=device-width, initial-scale=1"> <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/1.18.4/TweenMax.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/1.18.4/utils/Draggable.min.js"></script> <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css"> <link rel="stylesheet" type="text/css" href="test.css"> </head> <body> <div id="wrapper-id" class="wrapper"> <div id="item1" class="list-item2" > <canvas class="main" id="cropCvs1" width="1200px" height="675px" style="border: 4px solid red"></canvas> </div> <div id="item2" class="list-item" > <canvas class="sub"id="cropCvs2" width="1200px" height="675px" style="border: 4px solid orange"></canvas> </div> <div id="item3" class="list-item" > <canvas class="sub" id="cropCvs3" width="1200px" height="675px" style="border: 4px solid yellow"></canvas> </div> <div id="item4" class="list-item" > <canvas class="sub"id="cropCvs4" width="1200px" height="675px" style="border: 4px solid green"></canvas> </div> <div id="item5" class="list-item" > <canvas class="sub"id="cropCvs5" width="1200px" height="675px" style="border: 4px solid slategray" ></canvas> </div> <div id="item6" class="list-item" > <canvas class="sub" id="cropCvs6" width="1200px" height="675px" style="border: 4px solid blue"></canvas> </div> <div id="item7" class="list-item" > <canvas class="sub" id="cropCvs7" width="1200px" height="675px" style="border: 4px solid purple"></canvas> </div> <div id="item8" class="list-item" > <canvas class="sub" id="cropCvs8" width="1200px" height="675px" style="border: 4px solid white"></canvas> </div> </div> <script src="test.js"></script> </html> var container = document.querySelector(".wrapper");

  3. I want to resize the container while maintaining the ratio of the container according to the window size.But it was not easy because the x and y axes of the cell were fixed. How should I modify the code?
