I would like to create my own personal website using voiceover, in html or using Java Script. Is this possible? If so, how?
I used this website to relearn HTML and CSS:
It does a great job of guiding you through all the steps you need to know to make a website and also gives good tips on keeping it accessible for keyboards and screen readers.
I hand coded my website using TextEdit in plain text mode, making sure that smart quotes were turned off. Smart quotes will absolutely break HTML so be wary of that. It's really easy to set up in TextEdit.
I bought the Forklift FTP and use that to upload and maintain my websites and online files. There is an accessible program called Coda that I might buy when I get more into web coding; it's pricey, but includes an FTP and coding and file management system all in one, letting you do all the design and coding and uploading in one spot.
Hope these links work out for you and good luck! Also worth checking out DeQue University and following their class on web accessibility. It's free if your are blind or visually impaired, and will set you up for great accessibility knowledge and skills:
How does the Dapp app creator work? How do I make the app, like I want to make an app with audio descriptions on how to do certain things, meaning work a app, or do something in an app. After that, how do I publish the app, so other people can download it?
First I recommend you using HTML, CSS and Java Script. You can learn about all 3 programming languages from the link provided by one of the previous posters. If you have an iPad you can download the swift playgrounds app from the app store. The swift playgrounds app will teach you how to use the swift programming language. You won't be able to publish your app unless it is approved by Apple. Hope this helps and good luck!
