html5 - Use nth child in CSS3 -


i select each group of 3 elements first one

example :

<ul>     <li>1</li> <!-- 1 -->     <li>2</li> <!-- 1 -->     <li>3</li> <!-- 1 -->     <li>4</li>     <li>5</li>     <li>6</li>     <li>7</li> <!-- 1 -->     <li>8</li> <!-- 1 -->     <li>9</li> <!-- 1 -->     <li>10</li> </ul>

so have add background 1 1, 2, 3; 7, 8, 9; 13, 14, 15, etc .. don't have total amount of <li>

is there solution using nth-child() ?

yes, there solution using nth-child obviously.

li:nth-child(6n+1), li:nth-child(6n+2), li:nth-child(6n+3){   color: blue;   background-color: red; }

basicly 'nth-child' making kind of formula you. replace 'n' number check children work.

transpose - Maple isnt executing function but prints function term -

im using maple im in worksheetmode tried using maple input , 2d input , want transpose matrix a: := `<|>`(`<,>`(1, .5, -2), `<,>`(.5, 9/4+b, 5+3*b), `<,>`(-2, 5+3*b, 18+9*b+4*a)); b:= transpose(a); when exectute sheet dont translated values, there same input. matrix looks same input matrix plus function term. you can see picture in following link: why arent functions executed? meanwhile b:=a^+ doing right way , transposed matrix. other functions return function body instead needed values... if using 2d input mode (the default) space you've got between transpose , bracketed (b) interpreted multiplcation. rid of such space. also, either load package @ start of document like, with(linearalgebra): before calling transpose command package, or call it's full name like, linearalgebra:-transpose(b);
