0صور خلفية استجابة للمواقع

لقد تم مؤخرا استكمال بلدي المواقع وخادم الويب وإضافة موقع جديد (LoveCrete.org). أردت أن يكون صورة خلفية على LoveCrete وأدركت أن وبطبيعة الحال 1 لا يصلح جميع الشاشات. وفيما يلي ملخص لما كان تفكيري وماذا فعلت لتلبية احتياجات العديد من أحجام الشاشة واتجاهات.

I star­ted by mak­ing myself a little table of all the com­mon res­ol­u­tions used on أجهزة الكمبيوتر and tab­lets (in hori­zont­al ori­ent­a­tion). I decided to focus on this because most images are avail­able in land­scape so this is a sens­ible place to start.

I decided that I would place images cent­rally on the page and let the edges be lost off the edge of the screen in some instances. When a phone is used in por­trait ori­ent­a­tion it will load the image based on height (لا عرض) وسوف تفقد الكثير من كلا حافة الصورة. Doing it any oth­er way would mean need­ing images cropped to a totally dif­fer­ent shape or hav­ing a land­scape image “tile” on a tall screen, which is not desir­able.

The ratios of the max­im­um size image to make in each group were all around 1.6 with a few a bit high­er. To keep things sim­pler I decided to use a ratio of 16:10 for all images and came up with sizes to make accord­ingly.

This means in most cases the image will not be a per­fect fit to the screen size, but all screens will get some­thing very close and no screen will end up with some­thing too small. وهذا يعني أيضا مصدر الصورة يمكن حصدها ل 16:10 once and then mul­tiple sizes eas­ily cre­ated

As you can see I have grouped quite a few res­ol­u­tions and will then make 1 image that will cov­er all heights up to the largest height in that group. I will make sure the image is also wide enough for the max­im­um width such a height might be paired with on a nor­mal screen. I haven’t taken account of unusu­al con­fig­ur­a­tions like 21:9 mon­it­ors or mul­tiple screens — there has to be a lim­it some­where!

لان CSS uses the view­port or browser size and not the screen size land­scape screens need to use width rather than height — as on most sys­tems the top and bot­tom lose space to title bars etc whilst the width is usu­ally max­im­ised. لكن, for por­trait dis­plays it is bet­ter to use the height prop­erty. ويمكن القيام بذلك كما CSS can identi­fy the screen ori­ent­a­tion

ال CSS used then looks as fol­lows
