    <p>I was planning to use LESS css in my project (PHP). I am planning to use its nested <code>@media</code> query feature. I find that it fails to group the multiple media queries in the output css it generates.</p> <p>For example: </p> <pre> // LESS .header { @media all and (min-width: 240px) and (max-width: 319px) { font-size: 12px; } @media all and (min-width: 320px) and (max-width: 479px) { font-size: 16px; font-weight: bold; } } .body { @media all and (min-width: 240px) and (max-width: 319px) { font-size: 10px; } @media all and (min-width: 320px) and (max-width: 479px) { font-size: 12px; } } // output CSS @media all and (min-width: 240px) and (max-width: 319px) { .header { font-size: 12px; } } @media all and (min-width: 320px) and (max-width: 479px) { .header { font-size: 16px; font-weight: bold; } } @media all and (min-width: 240px) and (max-width: 319px) { .body { font-size: 10px; } } @media all and (min-width: 320px) and (max-width: 479px) { .body { font-size: 12px; } } </pre> <p>My expected output is (@media queries grouped)</p> <pre> @media all and (min-width: 240px) and (max-width: 319px) { .header { font-size: 12px; } .body { font-size: 10px; } } @media all and (min-width: 320px) and (max-width: 479px) { .header { font-size: 16px; font-weight: bold; } .body { font-size: 12px; } } </pre> <p>I would like to know if it can be done in LESS (PHP) it self or is there any simple PHP based CSS parser I can use to manipulate the output CSS to group and merge the @media queries. as shown in the below flow.</p> <pre> LESS file | V [LESSphp compiler] | V CSS file | V The CSS file generated would undergo my script written using CSS parser | V CSS file with similar @media grouped. </pre> <p>In case achieving grouped @media queries in LESS (PHP) is not an option I would like to know your suggestions on CSS parser (PHP) that can be used in the above flow.</p>

    1. COIt can't do this - it can't guarentee one media query will be matched and another one won't and whether one selector will override another one.

    2. COIf it is not possible to do it in LESS itself then I would like to know if there are any simple CSS parsers in PHP using which I can manipulate the output file so that I will programmatically achieve this.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
