Limit Input Characters using HTML CSS & JavaScriptHey friends, today in this blog you’ll learn how to Limit Input Characters using HTML CSS & JavaScript. Earlier I have shared a blog on how to create Random Password using pure JavaScript and now I’m going to create a program or input field that allowed users to enter a specified number of characters only.
 
In this program [Limit Input Characters], there is an input field on the webpage with an icon and counter number. This counter number informs the user about how many numbers of characters they can enter. At first, this input field is inactive with a grey border color but when you focus on the input field then the color of the border change into another color which means the input field is active now. When you start typing some characters in the input field then the color of the icon and counter also change into the same color as the input border color as well the counter start decreasing by the number of your entered characters.

In the video, you have seen the demo of this design or program and how I created this. As you know, I used JavaScript to make the counter dynamic and I believe these few lines of JavaScript were not much difficult to understand for you even if you’re a beginner. Except this all other parts including changing border color on focus in the input field and changing the color of the icon if user input some characters are purely created using HTML & CSS only.
 
This can be only possible using required attribute in the <input type=”text”> tag and :focus & :valid selectors in CSS. In this video, I have just shown you limit input characters in input but with the same codes, you can also do for the Textarea field.
