wordpress - Using onmouseover to change image size with wp_get_attachment_image involved -


below part of code use display multiple rows of products tiny thumbnails (35x35 pixels) next each product. admin page created, spreadsheet managing products, less space take better.

everything works great, have client "mouseover" view larger image. understand how "onmouseover" and/or work css achieve enlargement of image, that's traditional <img src... > element.

is possible alter or tap wp_get_attachment_image same effect? can't paste code <img> element because "not there", speak, type (sorry lack of terminology, assume function rather static code can work with).

or, there way not set array(35,35) , make <li> size container, make image fill container, , work element image alteration?

if ( $attachments ) {     foreach ( $attachments $attachment ) {        $thumbimg = wp_get_attachment_image( $attachment->id, array(35,35) );        $productlist .= '<li style="display: inline-block; vertical-align: top; margin: 0px; margin-right: 7px;">' . $thumbimg . '</li>';     } }

i've done before in 2 different ways:

1. display image background image

php: (note i've moved inline css make easier see code changes)

if ( $attachments ) {     foreach ( $attachments $attachment ) {         $thumbimg = wp_get_attachment_image_src( $attachment->id, array(35,35) );         $productlist .= '<li class="prodimgcontainer" style="background-image:url('.$thumbimg[0] .')"></li>';     } }

css:

.prodimgcontainer{     width: 35px;      height: 35px;      background-repeat: no-repeat;     background-position: center center;     background-size: 100%;      // inline css:      display: inline-block; vertical-align: top; margin: 0px; margin-right: 7px; } .prodimgcontainer:hover{     background-size: 105%; }

2. use overflow:hidden on container element "crop" visible portion of image

php:

if ( $attachments ) {     foreach ( $attachments $attachment ) {         $thumbimg = wp_get_attachment_image( $attachment->id, array(35,35) );         $productlist .= '<li class="prodimgcontainer">' . $thumbimg . '</li>';     } }

css:

.prodimgcontainer{     width: 35px;      height: 35px;      overflow: hidden;      // inline css:      display: inline-block; vertical-align: top; margin: 0px; margin-right: 7px; } .prodimgcontainer img{     width: 35px; } .prodimgcontainer img:hover{     width: 39px;     height: 39px;     /* move position of image remains centered */     margin-top: -2px;     margin-left: -2px; }

this work percentages, images fixed width, used dimensions it's clearer what's happening.

note:

these examples based on work have done, concept valid in both cases , should work, however, i've made code changes above off top of head hasn't been tested.

i found option 1 makes easier work image, if images different sizes or need responsive.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
