Gradient across path in SVG -


i have simple path within svg.

<svg     xmlns="http://www.w3.org/2000/svg"     xmlns:xlink="http://www.w3.org/1999/xlink" viewbox="0 0 61 57"      version="1.1" x="0px" y="0px">     <defs>         <style type="text/css"><![cdata[             ]]>         </style>     </defs>     <path id="pipe" d="         m8.0178,52.0035         l27.0178,52.0035         c42.4568,52.0035 55.0178,39.4425 55.0178,24.0035         l55.0178,8.0035         l43.0178,8.0035         l43.0178,24.0035         c43.0178,32.8255 35.8398,40.0035 27.0178,40.0035         l8.0178,40.0035         l8.0178,52.0035         z">     </path> </svg>

what i'd achive have 3 separate gradients or filling spaces:

  • the first 1 inner curve center of bended tube (curve).
  • the second 1 center area.
  • the third 1 center area outer curve of tube.

alternatively use single gradient multiple stop colors.

the following image illustrates wanted result: https://i.imgur.com/opefazt.png in case rectangles added illustrate gradient want use along whole curve.

i did research regarding advanced gradients in svg not able understand how apply them or if necessary. understand how apply radial , linear gradients rectangles or curves did not deliver expected result.

i found can apply gradient along svg path? creates gradient in tube left right (so say) , i'd top bottom.

do guys have ideas how solve this?

in general not possible create gradients flow along path.

however, in cases yours involve straight pieces , circular arcs, can achieve effect breaking shape sections. apply different gradient each part. use <lineargradient> straight sections, , <radialgredient> curved sections.

in example below, have used simplified gradient "pipe" effect. wish add more stops yours give better 3d effect.

angular - Ionic slides - dynamically add slides before and after -

hi i'm using ngfor create set of 3 slides while starting in middle i'm guaranteed able slide left or right on start. when slide right can simple listen reachedend , push slide array i'm looping. but have problem adding slide beginning. if same above , use e.g. array.unshift() or spread add item beginning, view think it's on position 0 , snaps view new slide. the code below work animates slide change index 1. slide = [0,1,2] //example loop slidechanged(event) { if(this.slides.isbeginning()){ this.slide = [this.slide[0]-1, ...this.slide]; this.slides.update(); this.slides.slideto(1) } } <ion-slides [initialslide]="1" (ionslidedidchange)="slidechanged($event)"> <ion-slide *ngfor="let item of slide"> <h1>slide {{item}}</h1> </ion-slide> </ion-slides> any appreciated! you can using ionslidenextend , ionslideprevend events slides . please

minify - Minimizing css files -

i want know how css files can minimized. currently, using external sites css minifier compress css files. however, after removing whitespaces, comments, etc, file sizes reduced 10-15%. how frameworks bootstrap manage make minimized versions kilobytes. as example, css is: body { background-color: #ff0; } the reduction goes 28 bytes 22 bytes other css files have lot more characters still smaller this. actually minifying code means it's remove thing code white space characters new line characters comments block delimiters it reduces amount of code has transferred on web , speed site load fastly.but unreadable format.

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
