If you have a Twitter account then you definitely know what is tweet box and how it looks like. In this project [Twitter Post Share Box or Tweet Box], on the webpage, there is a tweet box as you can see in the preview image. In this box, there is a typing area, some media icons, a characters limit counter, and a tweet button. At first, the counter will be hidden and the tweet button also disabled but once you start typing then there is visible the counter and the button also active/clickable.
In this tweet box, there is a limit of 100 characters which means you can type 1–100 length/numbers of characters. Once you crossed the limit then the over characters will start highlighting, the tweet button is again disabled and the counter color is also charged into red and it shows you how many characters that you have to remove to tweet or proceed.
