I am building user interface for responsive single page chat application using HTML and CSS. The interface must include a <form> element for submitting a message.
Inside the <form> element I have <textarea> element and <button> element as submit button. The button must have inside it two images one centered on the other, and after a lot of effort and searchs I managed to do that. The problem is that I want this <button> and <textarea> to be on the same line and vertically centered in the <form>. I tried and searched a lot for something that may help me but none of the results was what I need,some of the what I tried is based on the answers in the following link:
Vertically centering button using css
see my code in fiddle.
Note: I am not allowed using CSS frameworks and no IDs for styling.
I appreciate any help. Thank you!
