It’s important that we are able to add custom HTML to our theme. For example, even on our own website using our theme, we needed to add HTML code for our PayPal payments. Here is how we did it.
Every page or post has an area for “Custom Fields”. They are located at the bottom of edit page of your post or blog. You might need to click on the “Screen Options” tab on the top right to view your custom fields.
Once you see it, you can simply type in a name of you custom field, simply used as an identifier of the type of content you want to add. Then to the right, you can add in your raw HTML code.
Now go up to your text editor, and add in the following shorcode. [html name=”Your Custom Field Name”]
Simliar to this screen shot below. Now you have successfully added raw HTML to your page or post.
