# 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
|
|
* ```css
|
|
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
|
|
* Found useful site for Regex writing / testing https://regex101.com
|
|
* this specific address has regex for email validation https://regex101.com/r/uP2oL7/1
|
|
|
|
* CSS - The "!important" rule should only be used as a last resort - nuclear option
|
|
* better to do elementName.className when wanting to temp add a class to override some css (like say a border color)
