### Polyfilling NodeList.forEach for IE Compatibility

Source: https://github.com/spatialillusions/milsymbol-generator/blob/master/unitgenerator/index.html

This JavaScript snippet provides a polyfill for the `NodeList.prototype.forEach` method, ensuring compatibility with older browsers like Internet Explorer that do not natively support it. It checks for the existence of `NodeList` and the `forEach` method before implementing a custom iteration logic.

```JavaScript
if (window.NodeList && !NodeList.prototype.forEach) { NodeList.prototype.forEach = function (callback, thisArg) { thisArg = thisArg || window; for (var i = 0; i < this.length; i++) { callback.call(thisArg, this[i], i, this); } }; }
```

### Implementing Google Analytics Tracking - JavaScript

Source: https://github.com/spatialillusions/milsymbol-generator/blob/master/unitgenerator/index.html

This JavaScript snippet implements Google Analytics tracking for the website, ensuring that page views are recorded. It checks if the protocol is not 'file:' to prevent tracking local file access and initializes the Google Analytics object with a specific tracking ID and domain.

```JavaScript
if (location.protocol != "file:") {
  (function (i, s, o, g, r, a, m) {
    i["GoogleAnalyticsObject"] = r;
    (i[r] = i[r] || function () {
      (i[r].q = i[r].q || []).push(arguments);
    }),
      (i[r].l = 1 * new Date());
    (a = s.createElement(o)), (m = s.getElementsByTagName(o)[0]);
    a.async = 1;
    a.src = g;
    m.parentNode.insertBefore(a, m);
  })(window, document, "script", "//www.google-analytics.com/analytics.js", "ga");
  ga("create", "UA-46798131-1", "spatialillusions.com");
  ga("send", "pageview");
}
```

This CSS fragment defines styles for various UI elements within a military symbol generator, including select boxes, headings, input sections for options and styles, menu items with embedded images, and general controls like switches, sliders, and select inputs. It sets properties for layout, spacing, and visual presentation.

### Managing Symbol Overlay Scroll Behavior (JavaScript)

Source: https://github.com/spatialillusions/milsymbol-generator/blob/master/unitgenerator/index.html

This JavaScript function, `symbolOverlay`, dynamically applies or removes a 'scroll' class to elements with classes '.symbol' and '.content' based on the user's vertical scroll position and the browser window's inner height. It is invoked on window resize and scroll events to create a responsive visual effect, likely to fix or unfix symbols on the screen as the user scrolls.

```JavaScript
function symbolOverlay() { if (window.pageYOffset > 128 && window.innerHeight > 600) { document.querySelectorAll(".symbol").forEach(function (elm) { elm.classList.add("scroll") }); document.querySelector(".content").classList.add("scroll"); } else { document.querySelectorAll(".symbol").forEach(function (elm) { elm.classList.remove("scroll") }); document.querySelector(".content").classList.remove("scroll"); } }; window.addEventListener("resize", function () { symbolOverlay() }); window.addEventListener("scroll", function () { symbolOverlay() });
```
