Mizere Yoyendetsa

Miyambo yozungulira ndizo mafashoni omwe amalembedwa mwachindunji mu lemba la HTML. Mafilimu apamtima amakhudza kokha chizindikiro chokha chomwe akugwiritsidwa ntchito. Pano pali chitsanzo cha kachitidwe kameneka kakugwiritsidwa ntchito ku chiyanjano, kapena chikhomo:

Ulamulilo uwu wa CSS ungasinthe ndondomeko yoyenera kulembedwa pamalumikizidwe awa. Komatu sizingasinthe chiyanjano china pa tsamba. Ichi ndi chimodzi mwa zofooka zazithunzi zoyendetsera. Popeza amangosintha pa chinthu china, muyenera kutaya HTML yanu ndi mafashoniwa kuti mukwaniritse mapangidwe enieni a tsamba. Icho sichiri chochita chabwino kwambiri. Ndipotu, ndi sitepe imodzi yochotsedwera kuchokera m'masiku a malemba a "font" ndi chisakanizo cha kapangidwe ndi kalembedwe m'masamba.

Izi zimapangitsa kuti zikhale zovuta kuzilemba ndi zojambula zina, zomwe sizili mkati. Mwachitsanzo, ngati mukufuna kupanga webusaitiyi ndikusintha momwe chiwalo chimayang'ana zovuta zina pogwiritsa ntchito mauthenga a mauthenga , mafilimu apamtima pa chinthu chomwe chidzapangitsa izi kukhala zovuta kuchita.

Pamapeto pake, zojambula zolimbitsa thupi zimakhala zoyenera pokhapokha zitagwiritsidwa ntchito mochepa.

Ndipotu, kawirikawiri sindinagwiritse ntchito mafashoni apamtima pa tsamba langa.

Zosindikizidwa Zojambula

Zojambula zojambulazo ndizojambula zomwe zili mu mutu wa chikalata. Mitundu yowonjezera imakhudza malemba okha pa tsamba lomwe iwo alowetsamo. Apanso, njira iyi imatsutsa imodzi mwa mphamvu za CSS. Popeza tsamba lirilonse lingakhale ndi masitala

, ngati mukufuna kupanga kusintha kwina kulikonse, monga kusintha mtundu wa zizindikiro kuchokera kufiira kufiira, muyenera kusintha pa tsamba lirilonse, chifukwa tsamba lililonse limagwiritsa ntchito pepala lojambula. Izi ndizoposa machitidwe apakati, komabe zimakhala zovuta nthawi zambiri.

Mafilimu omwe amawonjezeredwa

za chiphatikizanso kuwonjezera chikhomodzinso cha khodi ku tsambali, zomwe zingapangitse kuti tsambalo likhale lovuta kuti liziyang'anira m'tsogolomu.

Phindu la mapepala apamwamba ndilo kuti katundu nthawi yomweyo ndi tsamba lokha, mmalo mofuna kuti mafayilo ena akunja azisakanizidwa. Izi zingakhale phindu kuchokera pawotchi yoyendetsa ndi momwe mukuwonera .

Mapepala Amkati Akunja

Ambiri a webusaiti masiku ano amagwiritsa ntchito mapepala apamanja akunja.Mawonekedwe apansi ndi mafashoni omwe amalembedwa m'ndandanda yosiyana ndiyeno amaikidwa pa zolemba zosiyanasiyana zamtaneti. Mafilimu akunja akunja angakhudze chilembo chilichonse chomwe ali nacho, zomwe zikutanthauza kuti ngati muli ndi tsamba la masamba 20 pomwe tsamba lirilonse limagwiritsira ntchito pepala lofanana (izi ndizochitika), mukhoza kusintha masomphenya onse za masambawo mwa kusintha kokha pepala lachilembo.

Izi zimapangitsa kuti kasamalidwe ka siteti ka nthawi yaitali kakhale kosavuta.

Zotsalira kumasamba a mawonekedwe akunja ndikuti amafuna masamba kuti azitenga ndi kutsegula mawindo awa akunja. Si tsamba lililonse limene lingagwiritse ntchito kalembedwe kalikonse mu pepala la CSS, masamba ambiri omwe angatenge tsamba lalikulu kwambiri la CSS kuposa momwe likufunira.

Ngakhale zili zoona kuti pamakhala zovuta zogwiritsa ntchito maofesi a kunja kwa CSS, zikhoza kuchepetsedwa. Zowona, maofesi a CSS ali chabe ma fayilo olemba, choncho nthawi zambiri si aakulu kwambiri kuyamba nawo. Ngati malo anu onse akugwiritsa ntchito fayilo ya CSS 1, mumapezanso phindu la chilembedwecho mutasungidwa poyamba.

Izi zikutanthauza kuti pangakhale kugwira ntchito pang'ono pa tsamba loyambirira maulendo ena, koma masamba otsatilawa adzagwiritsa ntchito fayilo ya CSS yosungidwa, kotero aliyense wogonjetsedwa anganyalanyaze. Maofesi a CSS akunja ndi momwe ndimapangira mawebusaiti anga onse.
