+# Allow Number Input To Accept Decimal Values
+
+Here is a number input element:
+
+```html
+<input type="number" id="amount" required class="border" />
+```
+
+This renders an empty number input box with up and down arrows which will, by
+default, increment or decrement the value by **1**.
+
+Of course, I can manually edit the input typing in a value like `1.25`.
+
+However, when I submit that via an HTML form, the submission will be prevented
+and the browser will display a validation error.
+
+> Please enter a valid value. The two nearest valid values are 1 and 2.
+
+If I want to be able to input a decimal value like this, I need to change the
+`step` value. It defaults to `1`, but I could change it to `2`, `10`, or in
+this case to `0.01`.
+
+```html
+<input type="number" step="0.01" id="amount" required class="border" />
+```
+
+Notice now that as you click the up and down arrows, the value is incremented
+and decremented by **0.01** at a time.
+
+If I want to maintain the step value of `1` while allowing decimal values, I
+can instead set the `step` value to be `any`.
+
+```html
+<input type="number" step="any" id="amount" required class="border" />
+```
+
+See the [MDN docs on number
+inputs](https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Elements/input/number)
+for more details.
