The Editorial article page is used for articles, pages with mostly text, on which you want to use the right side column to place widgets to include more information on the page, such as a contact person, related articles, or to add more navigation methods to the page.
You can insert images into your text using the Insert Sitecore Media button in the ribbon above. Set the width to the amount of pixels you want when you insert the image. Generally, we use 700px on Editorial (full width) article pages. As an example, this one's set to 500px:
If you want the image to fill the screen and be responsive (scale accordingly) on other devices, go the the HTML view in the bottom bar in the Rich Text Editor. Find your ‹img› and change the width in pixels to "100%" and delete the height. Like so: ‹img alt="" width="100%" src="/media/canals-and-cityscapes/amstel-en-gebouwen-omval-peter-elenbaas.jpg?la=en" /›
This particlar image needs a credit as well. You can add the credit in the HTML of the image so it shows when you hover over the image. Add "title="Image: Peter Elenbaas" to the tag, like so: ‹img alt="" title="Image: Peter Elenbaas" width="100%" src="/media/canals-and-cityscapes/amstel-en-gebouwen-omval-peter-elenbaas.jpg?la=en" /›
If the image in the Media Library had included an alt text, it would automatically populate in the HTML code. Here, you can see in the tag that the "alt" field has not been entered in the Media Library. You can add it here in the HTML, or when you insert the image into your article. This is always recommended for SEO purposes. Note, adding the alt text in the HTML does not add the alt text to the image in the Media Library.
Widgets on this page
The column on the right allows for a number of widgets, as displayed. All the possible widgets are:
Related Cards widget (keep in mind this widget displays by default along the bottom of the page, too)
Note: you can move widgets around within each place holder, but not between placeholders. I.e. you cannot move the Embed card under the Contact person widget or Recent articlelist, but you can move it under the Download, Rich Text and Related Cards widgets.
The placeholder below the text holds two widgets:
Form (Mvc form) (not recommended, use a Form page template instead)
The placeholders just under the social buttons are generally not used and some widgets here won't actually work.
The placeholder at the very bottom below the social buttons by default is the Related cards widget. The default widget gets populated based on the tags on the page.You can also manually set the cards in the Related cards widget.
Below is an Iframe widget. It allows you to display a webpage in a webpage.
