html - CSS - Blend edges of image with background image -


so have developing basic website , used images cool light effects change in color hits edge of page, image: enter image description here

so can see light in image reaches edge wanting know, there way blend edges in css or html , not that? i've looked on web , can't find relating problem...

thanks in advance!

there many ways accomplish that, way take care of edges when producing image. clear , simple. if page has black background, make sure have image background of same color. fade "light effect" same color before hitting edge using favorite image manipulation program.

i advice against producing image transparent background - image large , performance smacked.

if want experiment fading post-production, use css gradients make image seem fade off @ edges. or use (vendor specific) css3 toys box-shadow (see box shadow on mdn) produce inset, black shadow.

keep in mind though these tricks, specially on such huge images presented, have cost in browser performance (and user experience) , not supported (specially older browsers). also, many mobile devices not thank effects show.

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
