“Element queries are a new way of thinking about responsive web design where the responsive conditions apply to elements on the page instead of the width or height of the browser.
Unlike CSS @media queries, @element Queries are aware of more than just the width and height of the browser, you can write responsive conditions for a number of different situations like how many characters of text or child elements an element contains.
I am currently building a custom slides / template builder for a project, with a lot of moving parts and dynamic logic.
As there are repeating patterns within the slides, each pattern and its logic needs to be neatly separated. As the slides can be reordered and dropzones can be changed, I need to make sure logic doesn’t break and IDs get updated.
Before reassembling all templates, I am making sure that IDs match the slide and dropzone using a preg_replace_callback
One of the patterns is a simple tab setup, each has its unique ID defined like vl-tab_U1_S1_D1.
The function below passes the found matches through to the anonymous callback function in preg_replace_callback and offers outside data to the function using use($foo). The $dropzone object holds the current unit, slide and dropzone of the pattern, which can be used to replace the current ID with the correct one.
