how to add content in checkout page magento 2?

Question

I need to add my own content in this area which is checkout page. I can't find the phtml file.

Answer 1

This block rendered from summary.html of vendor/magento/module-checkout/view/frontend/web/template/summary.html

You can add your custom content after overriding this file in your theme

From

vendor/magento/module-checkout/view/frontend/web/template/summary.html

To

app/design/frontend/vendor/mytheme/Magento_Checkout/view/frontend/web/template/summary.html

Now run following commands

php bin/magento setup:static-content:deploy
php bin/magento cache:flush

Also need to flush browser cache

Answer 2

I may be wrong, but I think that to add content to specific areas of the order summary you would need to go to the checkout_cart_index.xml and add you blocks within the container.
