# Attributes

Additional information about attributes in \<emph\>LibreOffice Math\</emph\> is found here.

The \<emph\>acute\</emph\>, \<emph\>bar\</emph\>, \<emph\>breve\</emph\>, \<emph\>check\</emph\>, \<emph\>circle\</emph\>, \<emph\>dot\</emph\>, \<emph\>ddot\</emph\>, \<emph\>dddot\</emph\>, \<emph\>grave\</emph\>, \<emph\>hat\</emph\>, \<emph\>tilde\</emph\> and \<emph\>vec\</emph\> attributes always have a fixed size and do not become wider (longer) if they are above a long symbol. By default, the attributes are centered.

The only attributes which grow with the length of the symbol are \<emph\>overline\</emph\>, \<emph\>underline\</emph\> and \<emph\>overstrike\</emph\>.

For some character strings, it is possible that a line inserted with \<emph\>underline\</emph\> is too close to the character. In this case, an empty group can solve the problem: \<emph\>underline Q sub {}\</emph\> instead of \<emph\>underline Q\</emph\>.
