Text Formatting ⇒ White Border around displayed Formula

[zhenyaka]

Hello, can you help me with the following problem?

I use LaTeX at my site to insert formulas. Here is the template for it. It works fine, but if I try to insert standalone formula? The preview adds white spaces at left and at right of formula. $\frac{11}{12}$ works good, but in-line formulas has bad radical sign.

I need solution to insert displayed formulas without white spaces, but in-line formulas I need to. Can I solve it with one template or I need to use two different?

Hi Zhenyaka,

welcome to the forum!

You could insert the command \displaystyle right after the $ sign to get the bigger style within inline formulas.

Never use $$ … $$ for unnumbered displayed equations. Use \[ … \] as the correct LaTeX syntax.

Why? $$ described in all documentations

It is not nearly in all. And you should forget those which recommend it. This environment causes several spacing issues. And the most striking one can easily be demonstrated.

This environment simply discards the fleqn option. For correct math typesetting take a look at »Math mode«.
