How to make formula in the center of Web page , but keep left align in its body.

[余江涛]

just like this

i have found two ways to solve this , one is 

\begin{align}

& x+y+z \\

& +w

\end{align}

the other is

\[

\begin{array}{l}

x+y+z \\

+w

\end{array}

\]

but they are not available for large formula like this

\[

{{a}_{0}}=\left(\left(-120\,d\,s\,{k}^{2}\,\sqrt{-120\,d\,s+4\,{p}^{2}+12\,p\,r+9\,{r}^{2}}+8\,p\,{k}^{2}\,\sqrt{-120\,d\,s+4\,{p}^{2}+12\,p\,r+9\,{r}^{2}}\,r+8\,{r}^{2}\,{k}^{2}\,\sqrt{-120\,d\,s+4\,{p}^{2}+12\,p\,r+9\,{r}^{2}}+240\,d\,s\,{k}^{2}\,p+\\

360\,d\,s\,{k}^{2}\,r-16\,{k}^{2}\,{p}^{2}\,r-40\,{r}^{2}\,p\,{k}^{2}-24\,{r}^{3}\,{k}^{2}-\,b\,\sqrt{-120\,d\,s+4\,{p}^{2}+12\,p\,r+9\,{r}^{2}}\,r+3\,d\,q\,\sqrt{-120\,d\,s+4\,{p}^{2}+12\,p\,r+9\,{r}^{2}}-60\,b\,d\,s+2\,b\,p\,r+3\,b\,\\

{r}^{2}+6\,p\,q\,d+3\,d\,q\,r\right)\right)/\left(12\,d\,\left(15\,d\,s-\,p\,r-\,{r}^{2}\right)\right)

\]

Hi,

What result do you expect for the large expression?

Peter.

just like this, the equation is center of web page , and keep left align in its body.

you can assume the large equaiton is already have line-break marks "\\".

 I have found a quit weird solution by myself. wish you can provide a better solution.

first set the equation left align and set output format is HTML-CSS

```

 MathJax.Hub.Config({]

        jax: ["input/TeX", "output/HTML-CSS"],

        displayAlign:"left"

    });

```

then set the width of span.math to 0, so it's real width would be it's min-width

```

MathJax.Hub.Queue(function() {

    $("div.MathJax_Display span.math").css("width","0");

});

```

and add \\ for every equation, whether you wan't it has a line break or not.

```

\[

x+y+z\\

+w\\

\]

```

for equations you have add the line-breaks by yourself.

```

\[

x+y+z+w\\

\]

```

for equations you in a single line, to make MathJax generate a span with class of MathJax_FullWidth instead of MathJax.

thanks dvpc give a perfect solution.

\[{

x+y+z\\

+w

}\]

quote the whole equation in the {}, would make block line-breaks witch is left aligned.

Thanks for cross-posting Davide's suggestion for the community here.

Peter.
