Making multiple gradients using Less CSS -


this first project i've used less on, want make series of buttons have same general structure have different gradiated colours applied them.

i have default button style:

.button-regular (@origin: top, @start: #d2d2d2, @middle: #7a7a7a, @stop: #4d4d4d, @fallback: #3f4c6b, @border: #3c3c3c;) {   border-radius: 3px; color: @white; font-size: 13px; line-height: 18px; height: 36px; font-weight: normal; padding: 8px 15px 8px 15px; text-align: center;   background: @fallback;   background: -moz-linear-gradient(@origin, @start 0%, @middle 6%, @stop 100%);   background: -webkit-gradient(linear, left top, left bottom, color-stop(0%, @start), color-stop(6%, @middle), color-stop(100%, @stop));   background: -webkit-linear-gradient(@origin, @start 0%, @middle 6%, @stop 100%);   background: -o-linear-gradient(@origin, @start 0%, @middle 6%, @stop 100%);   background: -ms-linear-gradient(@origin, @start 0%, @middle 6%, @stop 100%);   background: linear-gradient(to bottom, @start 0%, @middle 6%, @stop 100%);   filter: progid:dximagetransform.microsoft.gradient(startcolorstr='@middle', endcolorstr='@stop', gradienttype=0);   border: 1px solid @border; }

i want overwrite colours each new instance of button using below:

input.lightblue {   .button-regular(top, #bfeef8, #40cdeb, #00bce4, #3f4c6b, #00b0d5;); }

but when create button:

<input class="lightblue" type="submit" value="search">

the original (grey) colours still show. there reason why colours aren't overwritten using new colours in new button instance, , there better way acheive i'm attempting?

i'm using less.js compile in-browser if makes difference.

what have there should work alright, need to

fix typo:

  • there semicolon (;) (after last color) in class definition

    input.lightblue {   .button-regular (top, #bfeef8, #40cdeb, #00bce4, #3f4c6b, #00b0d5); }

  • you call variable @white in mixin, need make sure define beforehand, or else write white instead.

some additional suggestions:

(i used random settings illustration). this

<input class="button default" type="submit" value="search"> <input class="button green" type="submit" value="search"> <input class="button red" type="submit" value="search">

where have button class define general button appearance. dunno, maybe this:

.button {     display: inline-block;     outline: none;     cursor: pointer;     text-align: center;     text-decoration: none;     font: 14px/100% arial, helvetica, sans-serif;     padding: .5em 2em .55em;     text-shadow: 0 1px 1px rgba(0,0,0,.3);      -webkit-box-shadow: 0 1px 2px rgba(0,0,0,.2);     -moz-box-shadow: 0 1px 2px rgba(0,0,0,.2);     box-shadow: 0 1px 2px rgba(0,0,0,.2); } .button:active {     position: relative;     top: 1px; }

and in less make mixins color gradients. this:

.gradient-mixin (@origin, @start, @middle, @stop, @fallback, @border) {   background: @fallback;   background: -moz-linear-gradient(@origin, @start 0%, @middle 6%, @stop 100%);   background: -webkit-gradient(linear, left top, left bottom, color-stop(0%, @start), color-stop(6%, @middle), color-stop(100%, @stop));   background: -webkit-linear-gradient(@origin, @start 0%, @middle 6%, @stop 100%);   background: -o-linear-gradient(@origin, @start 0%, @middle 6%, @stop 100%);   background: -ms-linear-gradient(@origin, @start 0%, @middle 6%, @stop 100%);   background: linear-gradient(to bottom, @start 0%, @middle 6%, @stop 100%);   filter: progid:dximagetransform.microsoft.gradient(startcolorstr='@middle', endcolorstr='@stop', gradienttype=0);   border: 1px solid @border; }  .button-make (@name:"default", @origin: top, @start: #d2d2d2, @middle: #7a7a7a, @stop: #4d4d4d, @fallback: #3f4c6b, @border: #3c3c3c;) {   @classname: ~"@{name}";   .@{classname} {     .gradient-mixin (@origin, @start, @middle, @stop, @fallback, @border);     &:hover {     .gradient-mixin(@origin, lighten(@start,10%), lighten(@middle,10%), lighten(@stop,10%), lighten(@fallback,10%), @border);     }     &:active {     .gradient-mixin (@origin, darken(@start,10%), darken(@middle,10%), darken(@stop,10%), darken(@fallback,10%), @border);     }   } }

and call them each color ... build classes each color buttons:

.button-make; .button-make ("green", top, #7db72f, #87d918, #4e7d0e, #7db72f, #538312); .button-make ("red", top, #ed1c24, #e93a3f, #aa1317, #ed1c24, #980c10);

here jsfiddle example of output.

but instead of defining colors in gradient hand can make more general mixin in less, takes 1 color , transforms colors use @stop,@start,@border,... using lighten, darken , other color operations.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
