What is the best way to implement changing the color and weight of the font through jquery?

Question

css

Good morning colleagues!
It is necessary to change the color of the text and the style of the text so that it becomes bold when clicking on the icons, such as in a Word. It is also necessary that this state can be saved. This is the first time I've done this and I'm interested in your opinion on how to implement it.
The algorithm is as follows: Click on the icons - the text becomes red, click - bold.

Thanks

Answer 1

hmm

Answer 2

It can be more elegant, but just hang up a click on the button and change css depending on the button. Like click->$().css (the property we want from the button)
