JavaScript tips

 I have been reading 'Cryptocurrencies all-in-one for dummies' by Kiana Danial et all. The book put me off buying some bitcoin. It seems so difficult to keep your 'private keys' secure. I learnt a lot about keeping online investing secure. There are more tips at:  bbingo.xyz/t

 If I upload files to my website then they do not always immediately appear when I look at my webpages in a browser. My hosting provider is 'Hostinger'. There are more tips at:  bbingo.xyz/t

 I have been adding more semantic HTML5 elements to my webpages. I have added 'header', 'section', 'main' and 'nav' elements. The 'accessiblity' course on 'web.dev' says to add semantic elements before adding ARIA attribues. I do use an ARIA label to distinguish two identical links. One link is big for small screens. The other link is small for big screens. There are more tips at:  bbingo.xyz/t

 I have been using 'accent-color' in CSS to set the background color of checkboxes and radio buttons. I found one quirk. I have a set of checkboxes with a CSS animation taking the 'accent-colors' through a rainbow. The background colors start off all in sync. But if I check and un-check some boxes then the colors get out of sync. It is as though un-checking a box restarts the animation afresh. There are more tips at: bbingo.xyz/t

 I enjoyed reading the course about HTML forms on Google's 'web.dev'. The course was an easy read and brought me up-to-date.  The course has lots of links to related articles There are more tips at:  bbingo.xyz/t

 I have been using the 'Wave' accessibility testing tool from 'webaim.org'. This tool is more thorough than 'Lighthouse'. So far 'Wave' has told me about:     - bad colour contrast that 'Lighthouse' had missed     - too long text of the 'alt' attribute of images     - the same links being repeated near to one another, making screen readers unecessarily repeat the link text     - text of a link being too general: 'more details'      - badly forcing the text of links to be underlined 'Wave' is a uiversity project supported by big tech companies and the U.S. government.

 I learnt a lot about how to design the HTML and CSS of a blog from starting a blog on 'blogger.com' and 'blogspot.com'. My own page of tips is one long list and has too many HTML elements which makes the browser slow to lay my page out. 'blogger.com' shows a paragraph for each post and shows the whole of the post when you select it. No-one reads my new blog except me. My blog is at: 'onecenttips.blogspot.com'.
