Posts are the entries that display in reverse chronological order on your home page. In contrast to pages, posts usually have comments fields beneath them and are included in your site's RSS feed. You don't have to use HTML when writing your posts. WordPress will automatically add it to your site, but if you do want control over different elements like boxes, headings, and other additional containers or elements, use HTML.
To write a post :
A. Go to dashboard >> post >> Add new
B. Start filling in the blanks
As needed :
1. Post Title
The title of your post. You can use any words or phrases. Avoid using the same title twice as that will cause problems. You can use commas, apostrophes, quotes, hypens/dashes, and other typical symbols in the post like "My Site - Here's Lookin' at You, Kid." WordPress will clean it up for the link to the post, called the post-slug.
2. Upload image
Allows you to upload an image
3. Post Editing Area
The blank box where you enter your writing, links, links to images, and any information you want to display on your site.
4. View post in visual or html view
You can use either the Visual or the HTML view to compose your posts.
5. Save Post Draft
Allows you to save your post as a draft / pending review 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.
6. Preview Post
Allows you to view the post before officially publishing it.
7. Publish Box
Contains buttons that control the state of your post. The main states are Published, Pending Review, and Draft. A Published status means the post has been published on your blog for all to see. Pending Review means the draft is waiting for review by an editor prior to publication. Draft means the post has not been published and remains a draft for you. If you select a specific publish status and click the update post or Publish button, that status is applied to the post. For example, to save a post in the Pending Review status, select Pending Review from the Publish Status drop-down box, and click Save As Pending. (You will see all posts organized by status by going to Posts > Edit). To schedule a post for publication on a future time or date, click "Edit" in the Publish area next to the words "Publish immediately". You can also change the publish date to a date in the past to back-date posts. Change the settings to the desired time and date. You must also hit the "Publish" button when you have completed the post to publish at the desired time and date.
8. Select a category
Allows you to select a category of your post. The general topic the post can be classified in.
