($(body).height() - 100)
```
Just... subtract? | If you don't want to calculate it each time and deducting 100, you can define a custom function that will do it for you:
```
function bodyHeight() {
return $("body").height()-100;
}
```
And then just call `bodyHeight()` instead of `$("body").height()`. |

] | When you create a spark you generate a voltage, $V$, between the two electrodes and a current, $I$, flows between them. Both the voltage and the current vary with time, so we need to write them as functions of time: $V(t)$ and $I(t)$.
If we have a current $I$ flowing across a voltage $V$, then the power is given by:

$$E = \int VI d t = \frac{CV^2}{2},$$

] | Fullscreen animation
====================
Now making a element fullscreen is pretty simple. It could be done with css alone.
```css
.content {
display: inline-grid;
width: 150px;
height: 100px;
background-color: cornflowerblue;
border-radius: 3px;
transition: width 2s, height 2s;
margin: 10px;

* JQuery: 3.6.0
* Css preprocessor: SCSS
* CSS Framework: Bootstrap 5.1.0

] | First of all, what is `nIntVal`?
Second, assuming its really `nIntValue`, when you enter the following loop:
```
while( nIntVal == 0 )
{
nIntVal += nTempVal;
cout<<nIntVal;
}
```
it is 0.
As for nTempVal, you are dividing 100 by `(1*2*3*...*25)`. You are using `int` type which means all valu... | `nTempVal = 0`. So the loop is not terminated.
You can easily find such error with `debugger` |
