CSS code can either be placed directly in a HTML file within the <style> </style> blocks or in a separate file with the .css extension. Chrome and Firefox have developer tools built-in. As the name suggests, the developer tools is suitable only for developers or people having a basic knowledge of the Cascading Style Sheets, HTML, JS code.
The Developer Tools of browsers allow you to test the responsive design of the website, add/modify the CSS code, see the performance of the web application, etc. Once you modify the code with the Firefox/Chrome developer tools, the browser will change the appearance of the HTML element you’ve edited.
The Cascading Style Sheets Editor tool of the browsers will suggest the CSS code/property when you enter the letter/character in a CSS class. As of now, there are over 500 properties. Understanding each property can take some time. Well, if you’re using WordPress, you don’t have to learn CSS. The following WordPress CSS editor will allow you to customize the HTML element as per your requirements:
CSS Hero is a powerful and one of the most popular WordPress CSS editor plugin. It displays several options, code editor, and the page you’re editing when you run it. To edit a block, you have to click on it. When you do so, CSSH will display the existing CSS code in the code editor and a list of properties that you can add to the CSS class without writing a single line of code. CSSH ships with a media query generator/manager tool, option to undo/redo changes, reset the changes you’ve made, etc.

It lets you see the “wireframe” of the page or the technical information of the selected element. Yellow Pencil costs $26.

SiteOrigin doesn’t have a fancy design like the above two plugins but it’s a good alternative to them. Also, the plugin is free. SiteOrigin is compatible with all themes available in the WordPress repository. It supports two modes visual and text. In the visual mode, SO will display changes you make with the visual editor tool on the fly. In the text mode, you’ll see a large text area on the screen.

To select the element, you should hover the mouse cursor on it and click the right button.
