some UI challenges to improve my web design skills

UIChallenges.txt

-- some UI that I would like to learn how it is done.

- Pluralsight - Edit Your Intrest page has bunch of 'pills' at the bottom that you could click and it will fill with a color to indicate selected.
- StackOverflow - tags - I like it how you can type on an input box and list of possible tags appear
- Toast Notification indicating something was saved or being saved or error
- Twitter - In update email notification - as you check boxes to opt in or opt out of email notification and circle with a tick mark appears indicating save was successful
- Angular survey - on angular survey, there was a page with list of items that was important, user could drag item up and down and change the order
- Facebook reactions
- sliding menu with animation (like in angular docs)


How do I align text/image in a center, if I have another text that has to be in the beginning. 
Something like "hamburger             Title(center)             "
