WORDPRESS GUIDE AS A BEGINNER

WORDPRESS GUIDE AS A BEGINNER

WordPress is very easy to understand however, I have figured out some important parts of WordPress that beginners may find confusing and I gave an explanation to them in such a way that you will understand them.

WordPress dashboard features the following menus; Posts, media, pages, comments, Appearance, plug-ins, users, tools, and settings but I am going to explain Appearance, Plug-ins, users, tools and settings. The rest are straight forward and not hard to comprehend.

Note: Some other menus will appear when you start downloading plug-ins but the above menus are just default.

(1) Appearance: As the name implies, changes made here will affect the appearance of your website. Appearance has sub-menus like themes, customize, widgets, menus, background, custom CSS, editor e.t.c.(sometimes the name of the active theme appears here e.g. Zerif Lite)

  • Custom CSS (Cascade Style Sheet) is used by people who knew and understood CSS to add additional effects to their website if the effect added by the theme is not enough. If you do not know anything about CSS please endeavor not to use it. (Learn CSS at W3school.com).
  • Widgets: A WordPress widget is a small block that performs a particular function. Take for example. On a website, it is a widget that displays recent posts on the sidebar. So you have to be familiar with it because you are going to use some of them for your own sidebar.
  • Editor: This part I strongly recommend you do not alter changes to, unless you are familiar with programming languages. This is where you will see all the codes that made up your website and if you change any code and replace it with a wrong code it may clash your site. If you add a wrong code it may also clash your site whichever way your site may clash and you wouldn’t want that to happen right? So for now it’s a no go area for you.

(2) Plug-ins: Plug-ins are web design tools specially designed by web development experts and coding masters/programmers to be used by the upcoming web masters to design professional websites without being so conversant with all the coding rules (i.e. not coding expert). Plug-ins behave in the following ways:

  • Plug-ins that appear to apply from the dashboard after downloading them e.g. (contact form, Table press e.t.c.). Some of these plug-ins appear on the dashboard but the configurations are done elsewhere such as: Under settings, appearance.
  • Plug-ins that appear under appearance are configured from there e.g. (light box)
  • Plug-ins that appear under settings are configured from there e.g. (page builder)
  • Plug-ins that do not appear in many of those places mentioned above but immediately forms a widget under appearanceàwidget e.g. some of the sidebar plug-ins fall under this category.

Under plug-ins we have sub-menus like Installed plug-ins, Add New and Editor.

  • Installed plug-ins displays the plug-ins you have installed both active and inactive plug-ins
  • Add New is used to add new plug-ins
  • Editor is code based, like I said earlier, it’s a no go area unless you know coding.

NOTE: Some plug-ins are applied through short code by copying the short code to the page or area where you want to use it. E.g. (Table, contact form, football fixtures)

(3) Users: Here we have sub-menus like all users, add new user and profile. When you click on all users you will see those people you have given the right to make posts on your site. Each of these categories of users has limitation like SUBSCRIBER can only read a post and comment on posts but can’t write a post on your website. EDITOR can edit posts. CONTRIBUTOR can only write and submit posts for verification before posting it on the website by the ADMINISTRATOR. AUTHOR also writes posts and finally ADMINISTRATOR is the commander in chief who checks and balances the activities of the above mentioned categories of user.

No explanation will be given to ‘add new users’ and ‘your profile’ because they are straight forward and easy to understand.

 (4) Tools: Under this we have import, export, export personal data, erase personal data. Import is used to import your documents like posts, comments e.t.c. from another website into your WordPress site and export does the opposite.

(5) Settings: Under settings we have; General, Writing, Reading, Discussion, Media, Permalinks and Privacy.

  • Writing: Here you set how your posts will be displayed, and the default category it should carry if you didn’t specify any category for the post. You also set if you want to be posting via your email.
  • Reading: You set how many posts your post page and syndication feeds should show at most, whether they should show full article or just summary of the post.
  • Discussion: This is straight forward to set up depending on what you want and how you want it.
