Notes

Overview

---

Aim of this document is to make notes of various things as I encounter them. Consider it learning from working through specific challenges or other exercises. Probably should be in a note app, or a wiki, or something, but for now they are here.

Think of it as a combination of learning, and tips and tricks. They will start unorganised, and then should be put into some semblance of order; where that is possible.

The Notes Themselves (unorganised)

• Now little difference between <input type="submit"> and <button>.

  • It used to be the case that IE6 didn't properly support it, so your website would look broken.
  • By default <button> implies type="submit"
  • A button can have child elements, an <input type="submit"> can't. (verify)

• When using em the increases are compound, so if you have a p, inside a div, inside body. The body font size is set in px. The div and p both set a font size using em to set a relative size, then that relative size would be

  • in div: body font size * font size em
  • in p: div relative font size * p's font size in em

  • body {
        font-size: 20px;
    }
    
    div {
        font-size: 2em; /* font size is 40px */
    }
    
    p {
        font-size: 2em; /* font size in this div is now 80px  */
    }
    

• Random aside: can't carry on a list after putting a codeblock inside a list
