Click on “Posts” and “Add New” button
Add content and images using blocks
A block consists of a Block Toolbar, a Block Settings Sidebar and the Block Content. Depending on the block’s purpose the buttons of the Block Toolbar will change and so will be settings items in the Block settings sidebar.
There are many block types for you to choose from. You can edit or move each block independently of other blocks, and individual blocks sometimes come with their own formatting settings for even greater control over layout and function.
The settings at the top of the block usually include formatting options as well as the option to change the block type ([1] in screenshot below).
In the editor’s sidebar you can switch between settings for the current block ([2] in screenshot below) and settings for the whole document ([3] in screenshot below).
Use gear or settings icon ([4] in screenshot), to hide and show editor’s sidebar on the right.
Document (Post or Page)
Select “Document” tab. It is where you can add tags and categories, choose a featured image, see and change the status of your post, and more — these are options that apply to the page or post as a whole.
Categories
The general topic of the post. It is typical for a blog to have 7-10 categories for content. Readers can browse specific categories to see all posts in the category. You can manage your categories by going to Administration Panel > Posts > Categories.
Save Draft
Allows you to save your post as a draft rather than immediately publishing it. To return to your drafts later, visit Posts – Edit in the menu bar, then select your post from the list.
URL Slug
You should see “URL Slug” or “post name” or “post slug” or just “slug” appeared after you saved the post.
Punctuation such as commas, quotes, apostrophes, and invalid URL characters are removed and spaces are substituted with dashes to separate each word. If your title is “My Site – Here’s Lookin’ at You, Kid”, it will be cleaned up to create the slug “my-site-heres-lookin-at-you-kid”. You can manually change this, maybe shortening it to “my-site-lookin-at-you-kid”.
Tags
These are micro-categories for the post, similar to including index entries for a page. Posts with similar tags are linked together when a user clicks one of the tags. Tags have to be enabled with the right code in your theme for them to appear in your post. Add new tags to the post by typing the tag into the box and clicking “Add.” You can also click on the “Choose from the most-used tags” link to see all of the tags used by the site.
Visibility
This determines how your post appears to the world. Public posts will be visible by all website visitors once published. Password Protected posts are published to all, but visitors must know the password to view the post content. Private posts are visible only to you (and to other editors or admins within your site).
