WordPress Advanced Topics
(What Are We Not Telling You?)
In this last tutorial in this series we will address these WordPress Advanced Topics:
- How To Create A Child Theme
- How To Customize CSS (Including Divi)
- Using The Divi Visual Editor
We will not go into any real detail here but we will briefly introduce these topics. If these are of special interest to our customers we can cover them in more detail in later articles.
How To Create A Child Theme
What is a child theme? Why would you want to create one? How do you create one? Rather than explain this here, please refer to this article that covers all the details: https://www.elegantthemes.com/blog/resources/wordpress-child-theme-tutorial
Please note that it is very important to keep your website theme, plug-ins and WordPress itself updated to the latest versions to benefit from the latest bug features and security enhancements.
How To Verify You Are Using A Child Theme
As shown in the accompanying screenshot, if you look in Appearance–>Themes in your dashboard it should show that you are using the child theme.
How To Customize CSS (Including Divi)
This is a very advanced topic and this level of WordPress tweaking is probably best left to Persson Technologies. This can get very complicated very quickly but we will cover the basics here. For more details there is a CSS tutorial here: https://www.w3schools.com/css/css_intro.asp
In the sections below we will cover two common methods used to customize objects using CSS.
If you want to easily add CSS for an item on a Divi page you can use the CSS settings in Divi to add an ID or a class to any items. You would use an ID if you only want your CSS entry to affect one item. You would use a class if you wanted your CSS entry to affect all the items on your page or perhaps across your entire site. Let’s say for instance you wanted to easily modify the color or size of all dividers on one page. That is one example of how this could be used. Of course you would not use the names I have provided here. Typically CSS objects are named using all lower case letters separated with dashes as shown here.
The other image provided here shows the CSS entry that adds the green gradient to the footer. This green gradient affect can be viewed in a screenshot provided elsewhere in this blog entry.
Using The Divi Visual Editor
Earlier in this tutorial series we covered the basics of how to use the Divi Builder by adding sections to the page, rows to the sections, and modules to the rows. To tweak each element on a page you would need to locate and open that item to access the settings. Once you open the control panel for that item you cannot view anything else on the web page.
Starting with the Divi theme version 3.0 (and Divi Builder 2.0) there is now a Visual Builder that makes it possible to see the entire web page at once and tweak anything on the page! There are more details here: https://www.elegantthemes.com/blog/theme-releases/divi-3)
Do we use this at Persson Technologies? As of this date (3-18-2017) we use it after the page is built and we are tweaking the page. It is very useful to be able to view the entire page at once and fine tune the spacing between different items or quickly locate and fix typos.
Are there things that can go wrong? One of the most dangerous scenarios to avoid as of this writing is using the Visual Builder in preview mode. When you are previewing the page it is possible to enter the Visual Editor (we think this is a bug). After you have entered all your changes and saved them if you exit the preview mode all your changes will be lost! If you have more than one session of the Visual Editor open for the same page, the last version in which you save your changes will become the “real” version that is written to the database. Between these two items we have lost a great deal of time – it is easy to make these mistakes. Also it is worth noting that the spacing between items is sometimes not accurately reflected in the Visual Editor. It is therefore useful to open the web page in another browser to view the changes as you are tweaking the spacing in the Visual Editor.
Overall the Visual Editor is an awesome time-saving feature that we love!
