# Addressing Siblings This is a more advanced concept and it's typically not needed frequently. So feel free to skip this section. As described in section [hierarchy](https://docs.zerowork.io/using-zerowork/using-selectors/how-to-build-custom-selectors/hierarchy "mention"), elements can be defined by their hierarchy if they follow each other in a 'narrowing down' fashion. That means they can't be on the same level. If you need to address a tag which is on the same level but cannot or is not intended to be addressed in a list (list as described here [lists-incremental-css-selectors](https://docs.zerowork.io/using-zerowork/using-selectors/how-to-build-custom-selectors/lists-incremental-css-selectors "mention")), you can use tilde \~ for loose sibling (any of the following elements on that hierarchy level) and + for exact sibling (the next element on that hierarchy level). \ \ This might be confusing at a first glance, so you might want to check the video below for a more hands-on demonstration. ### Video Tutorial: Siblings {% embed url="" %}
