hi, i need a little help here , how can i use a codepen “html+css+java” code to my wordpress post/pages?
Its not an easy thing to do if you are not familiar with WordPress hooks and filters and PHP.
This is going to take some reading and effort on your part to get this to work. It is worth it however, this type of task is essential for a WordPress Developer, its a core skill to know.
If you want to do Wordpress development, install this on your machine
Then install WordPress. Now you have a local copy of WP running. Then just go to the theme directory of WP, and make/play with your changes there using an IDE or text editor. When you’re happy it’s working, ZIP the whole theme directory and you can use that to upload to your production WP installation.
This is basically what a widget plugin is, and that takes some WordPress chops to do. But again, if you plan on working with WordPress in any serious way it is worth taking the time to learn how to do.
Maybe I misunderstood the OP. I thought he wants to do Wordpress development.
Yes, I know. I did this on my local WP installation running on my machine (via virtual AMPPS). In functions.php enqueued custom scripts and styles, then did an add_action, created the widgets_init, register new functions, etc. I just edit the PHP files directly, then refresh the browser… repeat. (Instead of editing php files, zipping, uploading to a remote WP installation, test, repeat, etc).
When finally everything is working, only then would I zip the entire directory, upload and do final testing on the remote WP install.
Are you sure you need Wordpress? What are you trying to make and what’s your goal? If you just want “a website” and you’re learning HTML etc. you’d be better off building a static site with eg; Jekyll.
Wordpress is very popular but running it well is a full time job (just google “wordpress hacked” to get a taste of all the things that can go wrong) and (in my opinion) unless you actually want to be a Wordpress professional, it’s just not worth the effort.
