I'm making an Opera extension and I want to get some images stored in the extension's path. What this plugin does is, on a specific web page, change the background image URL and some icons to custom icons within the extension.

CSS Grid: Create new row when child content overflows column width

I have a two column layout based on CSS grid. When the content of the second column exceeds 1fr I want to create a new row. As it currently stands, the content simply overflows the column. One requirement of this layout is that the items in the right menu column are in one row.

Where is the empire cms label template?

Course Introduction：The Imperial CMS tag template file is located in the /e/config/temptags/ folder in the root directory of the website. It is used to define the behavior of tags so that specific tasks can be performed when tags are inserted in the template file. The structure of the tag template includes parameters, logic and output parts. The parameters control the tag behavior, the logic performs tasks, and the output generates HTML code. For example, the tag template for displaying news articles contains the parameters id (specifies the article ID), info (controls the display information), and r (controls the number of repetitions). The logic obtains the article information from the database and outputs an HTML code containing the title, author, and content.

Create custom tags to extend HTML functionality

To learn more about custom tags, check out my article on using ShadowDOM to create encapsulated custom tags. What are custom HTML tags? For example, with HTML, you can use markup to display bold text. If you need a list, you can use a label and its sublabels for each list item. Tags are interpreted by the browser and work with CSS to determine how web content is displayed and how parts of the content behave.
