MathCSS

A verbose, responsive, and easy way to represent basic math and calculus by a few lines of HTML without the need for a heavier JavaScript library. Built exclusively in CSS using a block-chain technique.

Support soon to be added for :

• Character decorators (such as vectors)
• Display-line containers (such as \sqrt, \frac, etc)

What's MathCSS good for?

• Quick depictions of integrals, summations, products, and alike.
• Fast loading time. MathCSS uses no JS. None!
• Scalable, responsive design. MathCSS is built like a choo-choo-s train.
• Special math symbols without looking up the unicode.

What isn't Math CSS made for?

• While an all-CSS solution is nice, there are limits. MathCSS will not be able to scale as easily. If you need users to interact with your math, I highly recommend a Javascript engine like MathJax.

Usage

Getting Started

First, add the CSS file to your page:

<link href="path/to/math.css" rel="stylesheet">

And you're ready to go! Documentation is easy as provided below. Simply, add an equation attribute to begin as follows:

<div equation>
   <!-- Your equation will go here -->
</div>

Integrals, Products, Summations

The goal of MathCSS is so that your HTML reads like math. You can easily add integral, doubleintegral, tripleintegral, product, summation like such:

<div equation>
    <div integral>

    </div>
</div>

To specify bounds and input, simply use upperbound, lowerbound, and of attributes:

<div integral>
    <div upperbound>
        5x
    </div>
    <div lowerbound>
        39x
    </div>
    <div of>
        35x + 45
    </div>
</div>

upperbound, lowerbound, and of will only display correctly when inside integral, doubleintegral, tripleintegral, product, or summation.

Since upperbound and lowerbound attributes are absolute, the order in which you declare them doesn't matter.

Fractions, Derivatives (a special fraction), Partial Derivatives

MathCSS has built-in support for fraction, derivative (short fraction), and partial derivative.

<div equation>
    <div fraction>

    </div>
</div>

To specify top and bottom, simply use top and bottom attributes:

<div fraction>
    <div top>
        5x
    </div>
    <div bottom>
        39x
    </div>
</div>

Since derivatives are technically both a fraction and an operand, they behave like a fraction in MathCSS. For the term that is being derived, just follow the derivative with a term tag. For example:

<div derivative>
    <div top>
        dx 
    </div>
    <div bottom>
        dy
    </div>
</div>

<div term>
    35x + 45
</div>

MathCSS also tries to allow users to never have to look up the unicode for common math symbols. Hence, there is a built in partial derivative function, just exclude the special d's. And yup, partial derivative reads just like English, use two words, not one or hyphenated.

<div partial derivative>
    <div top>
        x 
    </div>
    <div bottom>
        y
    </div>
</div>

<div term>
    35x + 45
</div>

Limits

Creating limits involves just three parts, the variable variable, what it is approaching goingto, and the term represented by of. The following code below would render the limit of x approaching infinity of thirty-five x squared plus twelve x plus nine.

<div limit>
    <div variable>
        x
    </div>
    <div goingto>
        <hr infty>
    </div>
    <div of>
        35x<sup>2</sup> + 12x + 9
    </div>
</div>

HR Magic!

Using HTML's built in <hr> tag, we can easily add common math characters into our equation without the messy closing tags.

For example, if you want to show the integral from the upperbound of infinity to the lower bound of 2 pi, of 35x + 45, simply:

<div integral>
    <div upperbound>
        <hr infty>
    </div>
    <div lowerbound>
        2<hr pi> + 6
    </div>
    <div of>
        35x + 45<hr pi>
    </div>
</div>

The above code renders:

The tags <hr pi> and <hr infty> will automatically show. The available subclasses range from greek commons, discrete math symbols, and common figures. See the full list below. Simply use <hr [KEYWORD]> -- no </hr> necessary.

Operand and Values:

partial, pm, infty, approx, neq, leq, geq

Discrete Math:

forall, exists, nexists, in, notin, and, or, cap, cup, congruent, subsetleft, subsetright, notsubsetleft, notsubsetright, subsetorequaltoright, subsetorequaltoleft, notsubsetorequaltoleft, notsubsetorequaltoright

Greek Letters:

pi, alpha, beta, lambda, delta (more coming soon)

General Operands

If you need to add, subtract, multiply, or divide two terms in a sequence, use add, subtract, multiply, divide.

Note that these attributes will only display functionally within the general equation tag and not within a integral for spacing reasons.

For example:

<div equation>
    <div integral>
        <div upperbound>
            5x<sup>2</sup>
        </div>
        <div lowerbound>
            39x
        </div>
        <div of>
            35x + 45
        </div>
    </div>

    <div add></div>

    <div doubleintegral>
        <div upperbound>
            5y
        </div>
        <div lowerbound>
            3y
        </div>
        <div of>
            35y<sup>78</sup> + 45
        </div>
    </div>
</div>

Exponents

If you want to add exponents, use the standard HTML <sup></sup> tags:

<div integral>
    <div upperbound>
        5x<sup>2</sup>
    </div>
    <div lowerbound>
        39x
    </div>
    <div of>
        35x + 45
    </div>
</div>
