How we can create a visual box-shadow editor and copy the CSS values in a click? Solution: See this JavaScript Box Shadow Editor With Copy To Clipboard Values Feature.
Previously I have shared a JS image editor program, but it is a box shadow editor where you can edit shadow values by seeing changes visually. Basically, The box-shadow CSS property adds shadow effects around an element’s frame. You can set one and multiple effects separated by commas. A box shadow is described by X and Y offsets relative to the element, blur and spread radius, and color. And using JavaScript we can create a live editor for visualizing the preview.
Today you will learn to create a live shadow and editor with preview program. Basically, there is a box and a box-shadow you will see. And there are many controllers and options like color values of both box and its shadow, background color, h-offset, v-offset, blur, spread, opacity, and inset. There is a basic color picker to changing color, and number input to change values. Also, there you can see the CSS values and copy in a single click.
So, Today I am sharing JavaScript Box Shadow Editor With Copy To Clipboard Values Feature. There I have used HTML to create the layout, CSS for styling, and JavaScript for functioning. There I have not used any library or framework to create the editor, it is a pure JS program. This program will help to create a perfect box-shadow and copy the CSS codes of it. You can use this program on your website to create an online box-shadow editor and help designers.
If you are thinking now how this visual editor program actually is, then see the preview given below.
Preview Of Live Shadow Edit and Preview
See this video preview to getting an idea of how this program looks like.
Live Demo
Now you can see this program visually, Also you can see it live by pressing the button given above. If you like this program, then get the source code of its.

JavaScript Box Shadow Editor Source Code
Before sharing source code, let’s talk about it. Basically, There I have created 3 div sections: the first section for box, box-shadow and its color values, second for show CSS values and copy, and the third is for controllers of shadow. There I have used input and label to create controllers. Used number input for values, and color input to pick the color. Also in the HTML file, I have linked other files like CSS and JavaScript.
Now using CSS I have placed all the elements in the right place, as you can see in the preview. With CSS first I gave basic values like size, position, margin, padding, etc to the elements. Also, I gave default color values and other color values for buttons like copy. There I have used CSS @media query for responsive design and reduces some element’s size.
JavaScript handling here all the features of the program. There is copy to clipboard function, you can copy the CSS code just in a single click. JS fetched all the elements using document.querySelector command and stored in const. I used if{} else{} statements to declare conditions. There JS only changing CSS values dynamically according to action.
Left all other things you will understand after getting the codes, I can’t explain all in writing. For creating this program you have to create 3 files. First file for HTML, Second for CSS, and third file for JavaScript. Follow the steps to creating this program without any error.
index.html
Create an HTML file named ‘index.html‘ and put these codes given below.
