There is more than one way to add custom CSS code to a WordPress blog.

Today, I will explain the strengths and weaknesses of the two different methods that I propose to you, so that you are able to choose the one that suits you best.

But before, if you have never installed WordPress discover How to Install a WordPress Blog in 7 Steps et How to search, install and activate a WordPress theme on your blog 

Then back to why we are here.

How to find the items you want to customize

Once you have isolated the part of your WordPress theme you want to change (for example the title of an article), you will need to determine CSS properties applied to it so that you can make the appropriate changes. Fortunately, this process is not complicated.

The CSS uses selectors to determine which elements will experience the different specific changes. Usually, this is done by specifying a " class "Of an element (or DOM element). However, CSS can also be used to define the layout of an entire element (for example, the tag " ") or using the identifier of the tag.

Fortunately, popular browsers allow us to see the different selectors and declarations that are applied to page elements with just a few clicks. On Google Chrome, for example, you just need to highlight a specific part of the document and then right click, like in the following example.

blogpascher-inspection

Clicking on " Inspect element In the drop-down menu that appears, you will see the HTML code of the page in a new window with the inspected item highlighted in the window on the right (Or below). You can see an example below.

blogpascher-logo

The texts of these elements (or attributes) Highlighted in red show you the different specific styles applicable to the item that you had highlighted by inspecting the code.

For example, the element " font-size Tells you that the font displayed in the highlighted item is sized to 13 pixels. The descriptors are surrounded by braces and preceded by selectors. The name of the corresponding style sheet file is displayed just to the right of the selectors.

Once you have this information in mind, changing the style becomes easy. For example, if you want to change the font from 13px to 14px, you simply look for your style sheet file, the selector that corresponds to the one of the highlighted item. It is generally in this form: (« # .block-plugin-content information"). You can then modify the different values ​​of the attributes.

You can do the same thing on Firefox, just highlight a specific part of the page, right-click on the item, then select " Inspect element In the menu that appears.

How WordPress and CSS work together

It is a fact that WordPress themes are created differently. So, keep in mind that your WordPress theme might not be 100% compliant with what you read in the following sections.

That said, it is more than likely that the CSS used on your WordPress blog is located in a file called " style.css " This is the common name for a style sheet for any type of website, not just WordPress.

Now it's time to go through the different editing processes.

Method # 1: Editing the Style File of Your WordPress Theme

There are two ways to access your theme's style.css file.

The first is to do it from your WordPress dashboard. On the left side menu, select the menu " Appearence "And then" Publisher ».

Once you are on the editor page, you will see a list of files on a vertical bar on the right side of the page. Scroll through the list of files. You will see a file named " Style.css style sheet " at the bottom of the page.

If you click on the name of this file, it will be loaded and displayed in the editor in the middle. You can use this screen to edit the file.

The other way to find the stylesheet is to navigate through your hosting provider's operating system and locate the file in the WordPress theme's folder (using an FTP client). The exact location will vary depending on your hosting provider. In the example shown below, the name of the website (In our case thecare) Is a folder under the public_html folder.

Since WordPress is installed, you can see the wp-content folder in "thecare". The wp-content subfolder is another folder called " wp-themes“, Which is where all the WordPress themes are installed.

From this website uses a theme called " Newsletter », The style file« style.css Is located in the folder " Parent Newsletter ».
