You definitely might have played different games software, but were you aware that you can develop games using HTML, CSS, and JavaScript. Furthermore, I strongly believe that developing games is an excellent way to enhance your coding skills, as it requires using logic and problem-solving skills.
Required Steps For Developing This Software
To create this Number Guessing Game software, follow the given steps line by line:
- Create a folder. You can name this folder whatever you want, and inside this folder, create the mentioned files.
- Create anÂ
index.html file. The file name must be index and its extension .html
- Create a
style.cssfile. The file name must be style and its extension .css - Create a
script.jsfile. The file name must be script and its extension .js
Once you create these files, paste the given codes into the specified files.
First, paste the following codes into your index.html file.
<!DOCTYPE html>
