Hi,
I am Front End UI Developer, having expertise in Web 2.0 technologies - HTML5, CSS3, JavaScript, jQuery, and MVC frameworks (Angular 4). I have worked with Bootstrap 3 and 4 , foundation, materialize, and sematic for design purposes and building responsive web applications.
I have visited all the attached images and got how you want the language button to be and also the sidebar menu. I can work with you right now, I have hands on expertise in CSS and I can use its controls efficiently. Consider me
Thanks,
