I know this tutorial has been posted before but I get a lot of questions about it, so here is the tutorial with images.
STEP 1
Go to your custamization page.
Click “Pages” and then click “Add a page”.
STEP 2
After clicking “add a page” a window will pop up;
You need to select “custom layout” as shown in the image.
STEP 3
After choosing “custom layout”, you will need to write your page name where It is shown with little arrow.
Then you will need to paste the code after “Custom HTML”, it is also shown with another arrow.
STEP 4
Then you will create the page by clicking “create page” as shown below.
STEP 5
After creating page, wait a little and make sure you see the area I marked as “1”. DO NOT CLOSE THE PAGE WINDOW!
Then you will save the page with clicking “save page” which is shown in the area marked “2”.
The page window will close itself after saving the page. After it gets closed, you will save everything by clicking “save” as shown in the area “3”.
