The header will features:
- a new logo
- a new layout
- an improved search experience
- a button for a collapsible sidebar
- //a table of contents? will it be a sticky header? Stay tuned for more design iterations!//
Some of these features might require structural or architectural changes to MediaWiki Core.
Features are subject to change! Design is iterative and subject to user-feedback.
This task encompasses all the tasks related to building out the new header.
##Technical Prerequisites
- [] T237635 - Decide how feature management will work for the Desktop Improvements project inside Vector.
####layout
- [] T240489 - A conversation around the Vector DOM structure and whether we should change it.
- [] T239248 - Separate the header into a stand-alone component.
- [] 2BTASKD (design) - Do we have a responsive layout for the header?
####logo
- [] T232140 - Create a new logo implementation that can account for multiple types of logos (thin/long, square).
- [x] T114695 - Split out the current `$mwLogo` ResourceLoader module so it isn't loaded unnecessarily.
- [] 2BTASKD - Whether to use an `<img>` tag or a CSS background image for the logo.
- [] 2BTASKD [SPIKE] - Investigate how new logo SVGs can be created. Wikipedia has ~300 localized logos, and there are 12 Wikimedia projects to account for.
####search
- [] 2BTASKD - Search might be an area to experiment with a new front-end framework as advised by the FAWG.
- [] 2BTASKD - Design a new search UI.
- [] 2BTASKD - Consult with the Search Platform team to ensure their core metrics are not impaired by the new search UI.
- [] 2BTASKD - The personal menu needs to be vertically aligned with respect to the new search bar position and logo position
####menu button
//This feature should only be added to the header when the collapsible sidebar has been built//.
