### Using Latex on Blogspot

I have been looking for a way to incorporate Latex code on Blogspot to write math, and here is a great way of doing it.
It looks quite nice too, $\sum_{i=1}^n 2^i$

By default, the math, as a rendered image, is displayed within a border. The border can be easily removed by modifying the html content under layout -> edit html

.post img{
border:1px .......
......
}

Simply set the border attribute to 0px. I think this also means your uploaded images will no longer have a border, but you can probably give that up for the sake of Latex.

[Update on August 17, 2009] I don't like the size of the rendered image displaying the math, it creates white space between consecutive lines if the math is put in as inline, making a large blog entry with lots of inline math equations look ridiculous. Wordpress does a much better job in handling latex code. Blogspot should incorporate latex handling if it wants to be popular among bloggers who like to use math in their blogs.

So writing ${\textstyle \sum_{i=1}^n x_i}$ gives you $\textstyle \sum_{i=1}^n x_i$. Is that what you want?
