New in 2.5.0
- Added support for Matrixes
- Added support for display in white
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.
Support soon to be added for:
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 (you can use the
mathbox alias as well):
<div equation> div>
If you want the display to be entirely in white, add the class
white to the
<div equation class="white"> div>
Integrals, Products, Summations
The goal of MathCSS is so that your HTML reads like math. You can easily add
summation like such:
<div equation> <div integral> div> div>
To specify bounds and input, simply use
<div integral> <div upperbound> 5x div> <div lowerbound> 39x div> <div of> 35x + 45 div> div>
of will only display correctly when inside
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
derivative (short fraction), and
<div equation> <div fraction> div> div>
To specify top and bottom, simply use
<div fraction> <div top> 5x div> <div bottom> 39x div> div>
While MathCSS cannot support infinite fraction's within each other, it can go down a scope of 2. You can embed a subfraction in a fraction, but not a subfraction in a subfraction in a subfraction due to sizing constraints. For instace, the following code will work:
<div fraction> <div top> <div fraction> <div top> 35y + 4x div> <div bottom> 12x + 4z div> div> + y<sup>2sup> + <div fraction> <div top> 35x + 4y div> <div bottom> 12z + 4 div> div> div> <div bottom> <div fraction> <div top> 35x + 2x div> <div bottom> 11x + 4 div> div> + 5 + <div fraction> <div top> 35x + 4x div> <div bottom> 12x + 4 div> div> div> div>
If you ever need to enclose a fraction in a fraction in a fraction, it is optimal to use a de facto (x / y) notation - that helps with readibility anyway due the decreasing sizes of integer.
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> x div> <div bottom> y 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>
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>2sup> + 12x + 9 div> div>
Square Roots and Roots
You can add square roots easily using the
root attribute. You can also specify the degree of the root with
of for the term. The
degree tag is optional.
<div root> <div of> 35x + 45y<sup>2sup> + 23 div> <div degree> 4 div> div>
You can add vector wide brackets using
vector instead of
<div vector> 4x, 3 div>
Using HTML's built in
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:
will automatically show. The available subclasses range from greek commons, discrete math symbols, and common figures. See the full list below. Simply use
Operand and Values:
delta (more coming soon)
To add absolute value, you can either use the
u tag or use
with whatever is being absoluted. For instance:
``HTML -5 + -5 = 10
### 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: ```HTML5x239x35x + 455y3y35y78 + 45
If you want to add exponents, use the standard HTML
<div integral> <div upperbound> 5x<sup>2sup> div> <div lowerbound> 39x div> <div of> 35x + 45 div> div>
The inherent complexity of matrixes makes them a bit different syntactically in Math.css. Math.css supports matrixes up to the size of 8 rows and infinite (within reason) cols. First, you need to declare the type of matrix along with the number of rows.
Due to the limits of CSS, the amount of rows needs to be statically declared unlike the number of cols.
<div matrix two> div>
This will create a matrix of two rows. The key attributes
eight all work respectively.
Due to the need to dynamically size the width of entries for long entries, we need to insert things into a matrix on a column to column basis.
To make things easy, math.css ships with two different ways of inserting columns. The first is the b-a method, which encloses a tags (entries) with b tags (cols). For instance, if I wanted the matrix of two by two rows, with the first row being 6 and 12, and the second row being 4 and 5, we get this:
<div matrix two> <b> <a>6a> <a>4a> b> <b> <a>12a> <a>5a> b> div>
However, this can get tedious given the amalgam of tags necessary. Therefore, you can instead use the alternate
method where you separate each entry with an
tag. Therefore, nothing is enclosed.
<div matrix two> <b> 6 <hr> 4 b> <b> 12 <hr> 5 b> div>
If you want to add probability constructs like n choose k, simply use the
choose tag, similar to how you would construct a fraction. Using the tags
bottom for each part of the choose.
<div choose> <div top> 4 div> <div bottom> 3 div> div>
