3. Plugins or Tools to Customize WordPress Theme

To Customize a WordPress theme more easily, without messing up with codes, there are different types of Plugins or Tools available Free in the WordPress directory, you can directly install and start editing your WordPress website. These tools/plugins are usually called Page builders, with the right approach and skill one can easily design a professional website.

The only thing you have to do is to install a Page builder tool that is compatible with the theme and with an easy UI, start building a website as you like.

Similarly, Elementor is one of the most popular and widely used page builders available. It gained popularity for its simple User Interface, a lot of customization options, add-on support, and drag-drop feature.

4. Customizing WordPress Theme with Codes

Under the Appearance section of your dashboard, you have noticed a “Theme Editor” link below the background option. When you try to open it by clicking on the link, you will see a page showing all the codes of the theme. You will have access to the style.css and functions.php, just like any other theme file. If you have a good command of CSS or you are a Developer, then only you can make some changes to it.

The alternative way by which you can customize the WordPress theme by editing codes is by using an FTP client. Using, a File Transfer Protocol client, lets you download and upload all the theme files from the web server. The whole process is straightforward. First of all, you need to connect your FTP client (File Zilla) with your web server, access the theme files, download them, make some changes to them, and upload the same through the FTP client.  

However, if you are familiar with CSS and writing codes, you can easily edit your own theme, which is specially built for your website considering all the essential requirements. But, if you are working on some other themes which you are not familiar with. It is better you first create a child theme and make changes to it, rather than messing with the parent theme file.

We highly caution you, that if you are not familiar with coding or lack CSS knowledge, you should never mess with Theme files. Otherwise it can break or damage your website completely.

5. How to Carry out Editing Theme Files?

The first and foremost step while editing theme files is to figure out the codes and their relation with the features of the website. Once, you understand the codes and their connection, then you can carefully proceed further to make some edits to them.

5.1. style.css File

From the name itself, it is clear that this file mainly contains all the files that have codes for styling your website. Whether it is for layouts, colors, icons, or fonts. Let us take an example if you are looking forward to making some changes to your website layout, you need to access your style.css file and make changes to it. If you want to change the color theme of your website, you need to edit codes in your stylesheet.

But be cautious while making some changes to the style.css file. Because it is not necessary that whatever the code has been written is originating from where you might have been figured out. In most cases, some functions or codes are part of some other functions that might be on the hierarchy of the same page.

Hence, to overcome this situation, and find out an exact element that affects CSS, you can use the Inspect element tool available in Chrome. Right-click on the webpage and choose the “inspect” option. A new window with elements and codes will appear in the same tab located either at the side or bottom of the browser as shown in the picture below:

Finding CSS elements on a webiste

With the help of this inspect element tool, it will become easier for you to locate and target every element on the web page and edit or add CSS to it.

5.2. The functions.php file

A function file is one of the most essential files required to run and work on some essential features of your website. Hence, you will find this file in most of the WordPress themes available. It is responsible for most of the functions such as widgets, picture slides featured images, and so on.

Whenever you want to add or edit functional codes, you need to access the functions.php file of your theme. Writing codes on the function file turned out to be somewhat writing for plugins. Hence, it is better to write code for a plugin rather than just adding two-liner codes. Another thing you must be aware of is that the function file is well written in PHP, hence a good knowledge of PHP is highly required.

You cannot simply copy codes from the internet and paste them into your function.php file. Else, there is a high chance that it will have some error codes and bugs present, that can potentially damage your website.

6. Editing in third-party WordPress Themes

If you have chosen a third-party WordPress plugin rather than your own theme or installed it from the WordPress repository. In this case, if you want to make some edits or customize, you need to create a child theme first.

It is because, without creating a child theme, when you try to make some edits or add some codes, After Updating, it will overwrite the previous codes and all the previous data will be lost.

Let us check out, how come you can create a child theme in a simple way.

  • Step1: You of all with the help of the FTP client, you need to access the wp-content folder and open the theme file.
  • Step2: Create a New folder in the theme folder.
  • Step3: In the new folder, you need to create a Stylesheet and provide information to WordPress that it is a child theme of the parent theme.
  • Step4: Copy the files from the parent theme to the child theme, you want to make changes or customize.
  • Step5: Once you complete the above steps, you need to activate your child theme on your website.

When you create a Child theme and start to update the WordPress theme, WordPress will select the file with the higher-order in the hierarchy list of the child theme, instead of the files in the parent theme.

To better understand this, let us suppose you created a child theme with an archive.php file, if your parent theme has a category.php file, WordPress will use the category.php file first from the parent theme itself. If you intend to use tags, WordPress will use the archive.php file from the child theme instead of using the parent. It is so because archive.php is in our 2nd position on the hierarchy list.

Follow the Best Strategy to Customize the WordPress Theme

Customizing a WordPress theme seems pretty straightforward, but carrying out the whole process more reliably and securely is another task. Therefore, you need better planning or strategy to follow, so that you can minimize the risks of hacker attacks, website damage, or any data loss. Let us check out what are they:

1. If possible, Customize the WordPress theme Without Editing Code

Without any proper coding knowledge or skills, you should not mess around with theme files. Or else you can damage your website. Therefore, it is better to stick with the WordPress Customizer tool to edit themes. It is a lot better and safer option than coding or playing with delicate theme files.

2. Use a Staging platform to run tests before making it live

WPOven provides its customers with a dedicated staging platform, in all wordpress hosting agency plans, where developers or users can perform various tasks without making them live on their website. With the help of this platform, a user can perform all the tests such as trying new plugins, custom themes, or new designs, without fearing website break or damage.

It is somewhat like a mirror image of your live website, just for running tests and the changes you have made. It will help you to eliminate all the shortcomings of customization and once live you will be assured about its performance.

If you are not editing the theme files and using a customizer. In this case, even you can use a staging platform and make all the changes to see how it looks without disturbing the live website.

When you are done performing and running tests, once you are confirmed and finalized just push it live on your website.

3. Create a Responsive Theme design

As technology has evolved and smartphones have been introduced. Since then the dependency of users on smartphones for internet browsing has increased. According to some reports, smartphones receive more than 50% of the internet traffic word wide.

From this data, you can easily estimate, how it is important to optimize websites for different screen sizes to cover a larger audience. Similarly, you also need to optimize your Website Theme for the different sizes available.

Whatever you have made any change in your WordPress theme, such as a change in styling, applied new layouts, or added some features, it should look clear and responsive on mobile screens as well as on your desktop.

we have already, mentioned how users depend on smartphones, and due to this, even some search engines make it their search Engine ranking factor. Now, it becomes essential for websites to optimize for mobile phones to get better search engine rankings.

Even, the WordPress customizer has an option to view your design on different screen sizes.

4. Must-Have Accessibility

You must ensure, whatever customization you have made in your theme file, should be easily accessible to everyone. Especially for those, who have a certain degree of disability or are unable to sense objects. Make sure you create or customize the theme is not only meant for a healthy person with no disabilities but there are a lot of other factors such as theme color and font size you must consider to cover a larger audience.

It is because, changing font size or theme color might be difficult for some groups of people to determine, read and interact with content on your website.

As mentioned above, whether you make changes or customize the WordPress theme, ensure that it is easily accessible or not.

5. Abide by the rules of the WordPress Coding Algorithm

Whenever you made some changes by adding or removing some codes from theme files or if you are creating a theme file, make sure it should be clean and well structured just like professional coders. It must be abiding by the rules and standards of WordPress coding guidelines.

It helps to maintain a clean and well-structured code page that represents the quality and level of coding you have done. Even you can check out coding guidelines by some popular coding languages such as Php, java, and CSS for your reference. Read them carefully and implement them whichever you feel relevant.

In case, you are using a third-party theme that is well structured and well coded, make sure you also maintain the same standard while customizing it. It is a great step to mention comments along with the changes you have made. So that, in case you are customizing in the future, it will help you to identify it easily. Even, it will become easier for any other user to go through coding and understand it.

What to Do If You’re Unable to Customize Your Theme in WordPress?

Do you have ever imagined, what you can do, if you are unable to customize WordPress Theme or the customizer is showing some issues while using it? What if the customizer tool won’t show you options or the page shows some errors? Let us check out how you can resolve it.

1. Reinstall or Update

The issues with the customizer can be raised due to bugs or error codes present in the old version of WordPress core files, themes, or plugins. Therefore, you must find out the main culprit by checking the current theme, Plugin, or WordPress core files, and update them immediately if their latest version is available.

Outdated versions are not always the single culprit, but sometimes hacker attacks or compromises in security can also result in these types of issues. Hence, it is become essential to check regular updates of all the elements present in your WordPress website.

2. Conflict Between Plugins

Errors or issues can also be raised due to either compatibility issues with the plugin and theme or the two plugin scripts conflict with one another. The level of complexity will increase when you increase the installation of plugins. The more plugins you add greater the possibility of conflicts. Hence, it is a better practice to eliminate all the unnecessary plugins and install only those plugins which are critical for your website.

To figure out the culprit plugin, the best possible way is to deactivate all of them rather than uninstalling them and check if the WordPress Customizer is working well or not. If it works fine, then activate each plugin one by one again, and check with the customizer. At this point, when the customizer shows issues, you will have your culprit plugin.

However, you cannot stop at this point. You need to carry out further investigation once all the plugins are covered. It will help you ensure that the single plugin is responsible for the other plugins as well. Once, you find out all the possible culprits, immediately uninstall them or delete them completely from your WordPress Website. The alternate solution you can think of is to either wait for the update or roll back it to their previous version.

Whether to change the website icon, add navigation menus, change the theme color, or add a timeline. Alternatively, you have to edit theme files and add/remove complex codes. but before that, you have to create a child theme and make changes to it, activate it, run a test, and then push it to your live website.
