css - Why does the button element allow vertical-align: middle? -


as far i've been able read, vertical-align: middle; css attribute works on elements display option set table-cell.

so why vertical-align accepted on button element? have missed something?

the reason question of cause want mimic button behaviour, avoid using structure:

<div style="display: table">     <div style="display: table-cell; vertical-align: middle;">vertically aligned</div> </div>

according css 2.1 specification, vertical-align property applies “ inline-level , 'table-cell' elements”, , inline-level elements “ inline-level elements elements of source document not form new blocks of content; content distributed in lines (e.g., emphasized pieces of text within paragraph, inline images, etc.). following values of 'display' property make element inline-level: 'inline', 'inline-table', , 'inline-block'.”

the button element has display: inline-block in default style sheet html 4, , corresponds browser practice.

thus, vertical-align applies button elements.

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
