# 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.

Note took far to long, but site now using main for branch.

## 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)

-   Blah ... its been a while. Oops.
