Help me finish my very simple website (JS, CSS, Bootstrap, HTML)

Hi, I have built a simple website for my startup ([login to view URL]) using html, css, js and need help from someone knowledgeable to fix a few small bugs and add some new features (I am very new to web development). I know exactly what I want and have detailed requirements as well as some code samples - it’s just a matter of refactoring/adding to the current code which will not take long. Tasks to complete: Animate navbar hamburger toggle button – so that it becomes an “X” when you click it, the animation that makes it an “X” should be the same as the one on [login to view URL] (mobile site) ([login to view URL]). It shouldn’t have a background colour either when the mouse is hovering over it. Again, like the apple toggle button, the two icon bars should change colour when the mouse is hovering over it. Navigation menu that is shown after clicking hamburger toggle button – change this to cover the whole page, it should go in an upward direction (as my navbar is at the bottom of the page), it should be exactly the same as the navigation menu on the [login to view URL] (mobile) website but in an upward direction. On hover colour should change too. The navigation menu should also close when an option is selected (currently does not do this) Navbar logo/brand – in mobile mode/at reduced pixels, the logo is not aligned to the right all the way, looks like some padding comes into place which needs to be removed so that the logo is all the way to the right as it is on my desktop Media queries – Investigate issue, background image isn’t being stretched full screen across all browsers on desktop/laptop, check that tablet/phone media queries work too (they do as far as I know - just in case) Font for slogan “Car selling, without the hassle” – I have added the font required as a woff and ttf file to my /fonts folder but browsers can’t seem to find the font and show times new roman instead (when the font is not installed), the same browsers can find the font I have for the buttons but not the slogan. Think I have missed something simple somewhere? Sizing of modals on mobile/tablet – Need to make this responsive e.g. the contact us modal currently takes up the whole screen on my mobile and doesn’t render properly, can’t click the close button on mobile/tablet as it’s difficult to access, reduce the size of the modals/change layout on mobile/tablet Sell my car – create modal for this option with several views. The different views are to be shown based on the user input (very simple process flow). Every view needs the title “Sell My Car” at the top and a black background, with rounded edges. Should look exactly the same as the “Contact Us” modal in terms of formatting. There should always be a close button shown under the modal irrespective of the view displayed. This modal needs to be responsive and display correctly across desktop, mobile etc. SEO – Make my site SEO ready, currently have nothing for this These are the tasks for now which will not be difficult for anyone experienced therefore no high bids please (will be ignored). Will definitely have more work to do (some soon and some later) so looking forward to working with the winning bidder! Please let me know if you have any questions. Thanks. Gurdeep
