If you’re reading this article, you’re probably already a WordPress user and already have experienced the easy to use, the graphical user interface of the WordPress platform. If your website is based on a theme, I’m sure you discovered that the themes could have some limitations when using the graphical user interface.
Before editing any WordPress code, it is imperative to back up your website; then if any irreparable damage does occur, your website can be quickly restored.
Using a child theme is also a good idea, as this enables you to make localized modifications without changing the source code and changing any functionality of the parent theme. One of the main benefits of using a child theme is that any updates to your parent theme, including those from your theme developer don’t affect your modifications.
I am going to cover the four most common languages used in editing your theme below. The purpose of this section is mainly to give those who are not yet proficient with these languages an overview of their uses and where to start should they wish to learn.
HTML stands for Hypertext Markup Language and is used by web browsers to interpret and display text and images. HTML is one of the most fundamental languages to learn and is often the starting point when learning website design.
Java Script is mainly used in front end website development to make pages more dynamic by manipulating page elements that are not possible through HTML.
One of the main benefits of using JaveScript is that it runs inside a client browser and process commands on a computer rather than on a server; this reduces server load and makes your website run faster.
PHP is used for a whole host of applications and is open source. It is primarily used alongside dynamic data-heavy websites to collect form data, generate dynamic content, or send and receive cookies. PHP runs on a server, so it doesn’t use the users’ computer to run, which means your server processes these commands. As well as server-side scripting, PHP is used for command-line scripting, which means it does not need a browser to run. Command-line scripting is particularly useful for running complex commands or grouping commands together, so you don’t forget a particular syntax each time you have to write it.
CSS stands for Cascading Style Sheets and determines the look of your webpage, including fonts, colors, and layout. CSS also allows you to adapt your website for presentations on different devices such as mobile and desktop.
On a live website, you can access the Theme Editor under the Appearance menu. Here you can make changes to the design and structure of your theme. If you have followed the above advice and are using a parent/child theme combination, you can toggle between editing the two in the top right.
Once the necessary changes have been made, make sure you click on the Update File button at the bottom of the page.
If your theme editor is missing, there may be a third-party code editor on your WordPress dashboard, or there may be a security plugin hiding this option.
For the purposes of custom editing, you can call an existing file using the following script
Note: If you are editing the header and footer files of the template, I would strongly recommend using a child theme as WordPress often overwrites these on updates.
There are also third-party plugins that allow you to edit the header and footer without changing the source code such as Insert Headers and Footers or Header and Footer Script Loader.
Alternatively, you may wish to use the Customise option under Appearance. This option will allow you to edit the CSS through the WordPress graphical interface. Depending on your theme, there may also be a custom CSS editor built-in.
